Pull all StringTableCollection from a MenuItem

I want to create a MenuItem that will pull all StringTableCollection from google sheets.
But I can't find a way to do it. Here is my code so far:

Code (CSharp):

1.  
2. var tableCollections = LocalizationEditorSettings.GetStringTableCollections();
3. foreach (var tableCollection in tableCollections)
4. {
5.     foreach (var ext in tableCollection.Extensions)
6.     {
7.         // TODO: How to get GoogleSheets from extensions?
8.         var googleSheetService = ext as IGoogleSheetsService;
9.         if (googleSheetService != null)
10.         {
11.             var googleSheets = new GoogleSheets(googleSheetService);
12.             foreach (var sheet in googleSheets.GetSheets())
13.             {
14.                 googleSheets.PullIntoStringTableCollection(sheet.id, tableCollection, new List<SheetColumn>()
15.                 {
16.                     // TODO: retrieve mapping from TableCollection settings
17.                 });
18.             }
19.         }
20.     }
21. }
22.  

I can't find a way to retrieve googleSheets data from tableCollection.Extensions, and I can't find the mapping from TableCollection.

Any clues on how to achieve this?

 

Sorry I found what I need on this link: https://docs.unity3d.com/Packages/c...ion.Plugins.Google.GoogleSheetsExtension.html
