I think you might want to do something like this:

--This block of code will move our minimap addon icons to below the minimap in a custom frame
local btnblklist = { --these are the children of the minimap that we DON'T want to move to our button bar, that way when we look for other children, we only take addon icons
    ['MinimapMailFrame']            = true,
    ['MinimapBackdrop']             = true,
    ['GameTimeFrame']               = true,
    ['TimeManagerClockButton']      = true,
    ['MiniMapWorldMapButton']       = true,
    ['MiniMapTracking']             = true,
    ['MinimapZoomIn']               = true,
    ['MinimapZoomOut']              = true,
    ['QueueStatusMinimapButton']    = true,
    ['MinimapZoneTextButton']       = true
}
 
local ButtonHoldBarChildren = {ButtonHoldBar:GetChildren()}
local MiniMapChildren = {Minimap:GetChildren()}
local function moveMinimapButtons() --stolen from bdMinimap and changed to be more efficient
    ButtonHoldBarChildren = {ButtonHoldBar:GetChildren()}
    MiniMapChildren = {Minimap:GetChildren()}
    for k, v in pairs(MiniMapChildren) do
        if not btnblklist[v:GetName()] then --check against our table made above, only add things that we want in the bar
            table.insert(ButtonHoldBarChildren, v)
        end
    end
 
    local last = nil
    for i = 1, #ButtonHoldBarChildren do
        local f = ButtonHoldBarChildren[i]
        local n = f:GetName() or ''
        if ((f:GetName() and (strfind(n, 'LibDB') or strfind(n, 'Button') or strfind(n, 'Btn') or strfind(n,'AllTheThings')) and f:IsShown())) then
            if not f.skinned then
                f:SetParent(ButtonHoldBar)
                local r = {f:GetRegions()}
                for o = 1, #r do
                    if (r[o].GetTexture and r[o]:GetTexture()) then
                        local tex = r[o]:GetTexture()
                        r[o]:SetAllPoints(f)
                        if (hideTextures[tex]) then
                            r[o]:Hide()
                        elseif not strfind(tex, 'WHITE8x8') then
                            local coord = table.concat({r[o]:GetTexCoord()})
                            if coord == '00011011' then
                                r[o]:SetTexCoord(0.3, 0.7, 0.3, 0.7)
                            end
                        end
                    end
                end
 
                f.tbackground = f.tbackground or CreateFrame('frame', nil, f)
                f.tbackground:SetAllPoints()
                f.tbackground:SetFrameStrata('BACKGROUND')
                f:SetHitRectInsets(0, 0, 0, 0)
                f:HookScript('OnEnter', function(self)
                    local newlines = {}
                    for l = 1, 10 do
                        local line = _G['GameTooltipTextLeft'..l]
                        if (line and line:GetText()) then
                            newlines[line:GetText()] = true
                        end
                    end
 
                    GameTooltip:Hide()
                    GameTooltip:SetOwner(self, 'ANCHOR_TOPLEFT', 0, 6)
                    for k, v in pairs(newlines) do
                        GameTooltip:AddLine(k)
                    end
                    GameTooltip:Show()
                end)
                f.skinned = true
            end
 
            -- sometimes a frame can get in here twice, don't let it
            f:ClearAllPoints()
            f:SetSize(20, 20)
            if last then
                f:SetPoint('TOPLEFT', last, 'TOPRIGHT', 4, 0)
                f:SetPoint('BOTTOMRIGHT', last, 'BOTTOMRIGHT', f:GetWidth()+4, 0)
            else
                f:SetPoint('TOPLEFT', ButtonHoldBar, 'TOPLEFT', 0, 0)
                f:SetPoint('BOTTOMRIGHT', ButtonHoldBar, 'TOPLEFT', f:GetWidth(), -f:GetHeight())
            end
            last = f
        end
    end
end
--This block of code runs the moveMinimapButtons() once, about 1s after init 
--because some addons handle their minimap icons slightly after loading
local g = CreateFrame('frame')
g.elapsed, g.counter = 0, 0
g:SetScript('OnUpdate', function(self, elapsed)
    self.elapsed = self.elapsed + elapsed
    while (self.elapsed > 1 and self.counter <= 1) do
        moveMinimapButtons()
        self.counter = self.counter + 1
        self.elapsed = 0
    end
 
    if self.counter >= 2 then g:SetScript('OnUpdate', nil) end
end)

It probably isn't the most optimized code in the world, but it runs exactly twice on load in and shouldn't impact things after that. It should grab most buttons, but if for some reason you have an addon whose button doesn't, you could /fstack and get its name and add it to this line:

if ((f:GetName() and (strfind(n, 'LibDB') or strfind(n, 'Button') or strfind(n, 'Btn') or strfind(n,'AllTheThings')) and f:IsShown())) then
