You have to change the isEquip function at line 190 like this:

local function isEquip(itemID)
    local isEquip = select(9, GetItemInfo(itemID))
    local isRelic = select(7, GetItemInfo(itemID)) == "Artifact Relic" and true or false;
    
    if isRelic or (isEquip ~= "" and isEquip ~= "INVTYPE_BAG") then
        return true
    end
    
    return
end

Note: GetItemInfo returns the subclass string localized. You might change "Artifact Relic" for your client language
