i forgot the link
https://github.com/Ssesmar/MapNote-Test

i also tried it this way and I created a new file and tried this

local ADDON_NAME, ns = ...
 
local WorldMapDataProvider = CreateFromMixins(MapCanvasDataProviderMixin)
local WorldMapPinTemplate = ADDON_NAME .. 'WorldMapPinTemplate'
local WorldMapPinMixin = CreateFromMixins(MapCanvasPinMixin)
 
function WorldMapPinMixin:SetPassThroughButtons() end
 
_G[ADDON_NAME .. 'WorldMapPinMixin'] = WorldMapPinMixin
 
function WorldMapDataProvider:RemoveAllData()
    if self:GetMap() then
        self:GetMap():RemoveAllPinsByTemplate(WorldMapPinTemplate)
    end
end
 
function WorldMapPinMixin:OnLoad()
    -- The MAP_HIGHLIGHT frame level is well below the level standard
    -- HandyNotes pins use, preventing mouseover conflicts
    self:UseFrameLevelType('PIN_FRAME_LEVEL_MAP_HIGHLIGHT')
end
 
function WorldMapPinMixin:OnAcquired(poi, ...)
    local _, _, w, h = self:GetParent():GetRect()
    self.parentWidth = w
    self.parentHeight = h
    if (w and h) then
        local x, y = poi:Draw(self, ...)
        self:ApplyCurrentScale()
        self:SetPosition(x, y)
    end
end
 
function WorldMapPinMixin:OnReleased()
    if self.ticker then
        self.ticker:Cancel()
        self.ticker = nil
    end
end
 
function WorldMapPinMixin:ApplyFrameLevel()
    -- Allow frame level adjustments in POIs even if the current frame level
    -- type has a range of only 1 frame level
    MapCanvasPinMixin.ApplyFrameLevel(self)
    self:SetFrameLevel(self:GetFrameLevel() + self.frameOffset)
end

------------------------------ HANDYNOTES HOOKS -------------------------------
-------------------------------------------------------------------------------
 
-- HandyNotes removes its data provider from the world map when the global
-- enable/disable checkbox is toggled at the top of its UI window. We need
-- to do the same thing here or our paths will still display.
 
local OnEnable = HandyNotes.OnEnable
local OnDisable = HandyNotes.OnDisable
 
function HandyNotes:OnEnable()
    OnEnable(self)
    if not HandyNotes.db.profile.enabled then return end
    WorldMapFrame:AddDataProvider(WorldMapDataProvider)
end
 
function HandyNotes:OnDisable()
    OnDisable(self)
    if WorldMapFrame.dataProviders[WorldMapDataProvider] then
        WorldMapFrame:RemoveDataProvider(WorldMapDataProvider)
    end
end
 
ns.WorldMapDataProvider = WorldMapDataProvider

and added

ns.WorldMapDataProvider:RefreshAllData()

to the main file under OnEnter and OnLeave. but it doesn't work
