Programs are stupid. You have to tell them exactly what you want. Maybe something like: (Left buton down, shift-key down = drag. right button = hide button. left button no shift-key toggle show/hide the frame (f))

local addonName, addon = ...
 
local CELL_WIDTH = 400
local CELL_HEIGHT = 80
local NUM_CELLS = 2
 
local data = {}
 
local f = CreateFrame("Frame", "SimpleScrollFrameTableDemo", UIParent, "BasicFrameTemplateWithInset")
 
-- Create the button here
local btn = CreateFrame("Button", nil, UIParent, "UIPanelButtonTemplate")
 
local function updateData() --commented out because addon.db hasn't been created... in the code at least
    wipe(data)
    for _, item in ipairs(addon.db) do
        tinsert(data, {item.announce[GetLocale()], item.icon, item.name})
    end
end
 
f:SetSize(CELL_WIDTH * NUM_CELLS + 80, 600)
f:SetPoint("CENTER")
f:Hide()
f:SetMovable(true)
f:SetScript("OnMouseDown", f.StartMoving)
f:SetScript("OnMouseUp", f.StopMovingOrSizing)
 
-- I added this OnHide script
f:SetScript("OnHide", function()
    btn:Show()
end)
 
f.scrollFrame = CreateFrame("ScrollFrame", nil, f, "UIPanelScrollFrameTemplate")
f.scrollFrame:SetPoint("TOPLEFT", 12, -32)
f.scrollFrame:SetPoint("BOTTOMRIGHT", -34, 8)
 
f.scrollFrame.scrollChild = CreateFrame("Frame", nil, f.scrollFrame)
f.scrollFrame.scrollChild:SetSize(100, 100)
f.scrollFrame.scrollChild:SetPoint("TOPLEFT", 5, -5)
f.scrollFrame:SetScrollChild(f.scrollFrame.scrollChild)
 
local content = f.scrollFrame.scrollChild
content.rows = {}
 
local function updateList()
    for i = 1, #data do
        if not content.rows[i] then
            local button = CreateFrame("Button", nil, content)
            button:SetSize(CELL_WIDTH * NUM_CELLS, CELL_HEIGHT)
            button:SetPoint("TOPLEFT", 0, -(i - 1) * CELL_HEIGHT)
            button.columns = {}
 
            button.columns[1] = button:CreateFontString(nil, "ARTWORK", "GameFontHighlight")
            button.columns[1]:SetPoint("LEFT", (0) * CELL_WIDTH, 0)
 
            button.columns[2] = button:CreateTexture()
            button.columns[2]:SetPoint("LEFT", 410, 0, (1) * CELL_WIDTH, 0)
 
            button.columns[3] = button:CreateFontString(nil, "ARTWORK", "GameFontHighlight")
            button.columns[3]:SetPoint("LEFT", 480, 0, (2) * CELL_WIDTH, 0)
 
            content.rows[i] = button
        end
 
        content.rows[i].columns[1]:SetText(data[i][1])
        content.rows[i].columns[2]:SetTexture(data[i][2])
        content.rows[i].columns[3]:SetText(data[i][3])
 
        content.rows[i]:Show()
    end
 
    for i = #data + 1, #content.rows do
        content.rows[i]:Hide()
    end
end
 
 
-- Set your button options here
local btn = CreateFrame("Button", "Hubb777MovingButton", UIParent, "UIPanelButtonTemplate") 
btn:SetPoint("CENTER")
btn:SetSize(100, 40)
btn:SetText("Click me")
btn:SetMovable(true)
btn:RegisterForDrag('LeftButton')
btn:RegisterForClicks("AnyDown", "AnyUp")
btn:SetUserPlaced(true)
btn:SetScript('OnDragStart', function(self, button, down)
    if button == "LeftButton" and IsShiftKeyDown() then
        self:StartMoving()
    end
end)
btn:SetScript('OnDragStop', function(self)
    self:StopMovingOrSizing()
end)
btn:SetScript("OnMouseUp", function(self, button, ...)
    if (button == "RightButton" and self:IsVisible()) then
        self:Hide()
    elseif button == "LeftButton" and not IsShiftKeyDown() then
        updateData()
        updateList()
        f:Show()
    end
end)
 
SLASH_HUBB1 = "/hubb"
SlashCmdList["HUBB"] = function(msg)
    updateData()
    updateList()
    f:Show()
end

You possibly want a way to get the button back after it's hidden other than a /reaload but may not, it's not clear?
