I have a mergerfs/snapraid pool on an Ubuntu 22.04 Lts server, and I need it to be recognized by nextcloud.

In the nextcloud container, I activated the external storage, but when trying to configure it, I get a message that I don't have permission.  But the only existing account in the container is the administrator, who in my understanding should have full power over it.

Note: Google translation, I speak Portuguese.
