copilot app is unable to edit an excel file and save a new version

I asked copilot to review an excel file I created and add worksheets with dashboard etc; it does the analysis, suggests the solution but when I ask to save a new edited version comes up with all kinds of limitations..  example of message : 

I need access to the physical workbook file in the execution workspace, not just the extracted workbook content that I can read.

What I currently have is access to the contents of "book2" , including all sheets and rows

What I do not have is a file path that allows me to save a modified workbook and return a new Excel file.

This is exactly the distinction you were asking about earlier:

• ✅ I can inspect and analyse "book2". 
• ✅ I can design the full V2 architecture you specified.
• ❌ In this session I cannot yet create and return the modified .xlsx because the actual uploaded file is not available in the workbook-editing workspace.

I save files on OneDrive and have MS365 Family subscription

, similar limitations with all MS files

is it a licence issue?
