If you use the default service account on your compute instance, you have to update the scopes; add all or only the Cloud Scheduler one.

If you don't use the default service account, you haven't scopes to select (scopes selection is a legacy mode, no longer available with new feature).

Note You have to stop the VM, change the scopes/service account and then restart the VM
