Dataflow Entity not visable in PowerBI Desktop

Hello,

I have recently added new dataflow and data entity by copying M code from Desktop version and paste into Data Flow of Workspace, now I can see dataflow from PowerBI desktop App but can't see entities are nested under it ?? do you have any idea? even after did refesh and data refresh many time, close and reopen PBI Desktop App?

Please check code below and advice ?

let
  Source = SharePoint.Files("https://XX.sharepoint.com/sites/XX/", [ApiVersion = 15]),
  #"Filtered hidden files" = Table.SelectRows(Source, each [Attributes]?[Hidden]? <> true),
  #"Invoke custom function" = Table.AddColumn(#"Filtered hidden files", "Transform file", each #"Transform file"([Content])),
  #"Renamed columns" = Table.RenameColumns(#"Invoke custom function", {{"Name", "Source.Name"}}),
  #"Removed other columns" = Table.SelectColumns(#"Renamed columns", {"Source.Name", "Transform file"}),
  #"Expanded table column" = Table.ExpandTableColumn(#"Removed other columns", "Transform file", Table.ColumnNames(#"Transform file"(#"Sample file"))),
