Can't access Google Drive via external storage app

I installed Nextcloud 16 stable via snap. Afterwards, I enabled the external storage app for Google Drive. I created the login credentials and I was able to add them in next cloud (they appear as green).

But when I try to access my Google Drive via Nextcloud I get this error:

"External mount error

There was an error with message: Empty response from the server. Do you want to review mount point config in admin settings page?"


Anyone knows what the problem is?
