Data Migration says 'Add accounts to start migration' but I have

I have been trying - unsuccessfully - to migrate  15 new users from Google Workspace to Zoho. I have set up the API correctly, filled everything in, created the new users in Zoho - but when I go to run the migration tool it says "Add accounts to start migration" and  won't proceed.

I added the accounts about an hour ago - they're all there - but without any daya. Why is this happening.

Please suggest a solution.

Thank you.
