Can't load workbook in ms 365office excel

Anyone having trouble connecting to Microsoft 365 Excel? I have connected and used an outlook.com account which is a free office365 account. When I successfully connected, I tried to download the Workbook to use it, but it did not appear even though it was already created.

Hello @ithikorn_thitinavakh ,

What error do you see in the workbook dropdown?

i connect already but in workbook can’t show anything
