I tried combining my code with yours. But it still doesn't work.

local addonName, addon = ...
local frame = CreateFrame("Frame", "QuestCompletionFrame", UIParent)
frame:SetSize(100, 100)
frame:SetPoint("CENTER")
frame:EnableMouse(true)
frame:SetMovable(true)
frame:RegisterForDrag("LeftButton")
frame:SetScript("OnDragStart", frame.StartMoving)
frame:SetScript("OnDragStop", frame.StopMovingOrSizing)
 
local text = frame:CreateFontString(nil, "OVERLAY", "GameFontNormal")
text:SetPoint("CENTER")
 
local Quests_Completed = Quests_Completed or {}
 
local function QuestTurnedIn(...)
    local questID, xpReward, moneyReward = ...
    local isCompleted = C_QuestLog.IsQuestFlaggedCompleted(questID)   -- Returns true
    print("Quest: ", questID,"XP: ", xpReward,"Money: ", moneyReward,"Completed: ",isCompleted)
    Quests_Completed[questID].Completed = isCompleted
end
 
local function QuestAccepted(...)
    local questID = ...
    local questLogIndex = C_QuestLog.GetLogIndexForQuestID(questID)
    local info = { C_QuestLog.GetInfo(questLogIndex) }
    print("Accepted Quest: ", questID, info["title"])
    Quests_Completed[questID] = info
end
 
frame:SetScript("OnEvent", function(self, event, ...)
    if event == "PLAYER_LOGIN" then
        local completedQuests = {}
        local questIDs = {70893, 71995}
 
        for _, questID in ipairs(questIDs) do
            local isCompleted = C_QuestLog.IsQuestFlaggedCompleted(questID)
            completedQuests[questID] = isCompleted
        end
 
        local localization = {
            ["enUS"] = {
                ["quest70893"] = "|cFFDEB887Community Feast:|r",
                ["quest71995"] = "|cFFDEB887Trial of the Elements:|r",
                ["yes"] = "|cFF1EFF00Complete|r",
                ["no"] = "|cFFDC143CIncomplete|r"
            }
        }
 
        local locale = GetLocale()
        local locStrings = localization[locale] or localization["enUS"]
 
        local questStatus = locStrings["quest70893"] .. " "
        if completedQuests[70893] then
            questStatus = questStatus .. locStrings["yes"]
        else
            questStatus = questStatus .. locStrings["no"]
        end
 
        questStatus = questStatus .. "\n" .. locStrings["quest71995"] .. " "
        if completedQuests[71995] then
            questStatus = questStatus .. locStrings["yes"]
        else
            questStatus = questStatus .. locStrings["no"]
        end
 
        text:SetText(questStatus)
    elseif event == "QUEST_TURNED_IN" then
        -- Triggers when pressing Complete Button
        QuestTurnedIn(...)
    elseif event == "QUEST_ACCEPTED" then
        -- Triggers before Pressing Accept Button
        QuestAccepted(...)
    end
end)
 
frame:RegisterEvent("PLAYER_LOGIN")
frame:RegisterEvent("QUEST_TURNED_IN")
frame:RegisterEvent("QUEST_ACCEPTED")
