Hi ​@Elena Moiseeva, thanks for reaching out!

Did you ever get edit access to the file? If the client that invited you to the file was an admin or existing editor with "can edit" permissions, you typically should have been granted a full seat immediately to allow editing, depending on the team's available seats and settings.

If you did not receive edit access right away, usually refreshing your tabs is enough to trigger the recent change. If you’re still having issues, please let us know.
