No Recovery Key after use Master Key for Only Office

Hey,

i used the command for get a Master Key

Create a new master key. Use this when you have a single-sign on infrastructure. Use this only on fresh installations with no existing data, or on systems where encryption has not already been enabled. It is not possible to disable it:

occ encryption:enable-master-key

Now i cant create a recovery Key

Enabling Users File Recovery Keys

If you lose your Nextcloud password, then you lose access to your encrypted files. If one of your users loses their Nextcloud password their files are unrecoverable. You cannot reset their password in the normal way; you’ll see a yellow banner warning “Please provide an admin recovery password, otherwise all user data will be lost”.

Why?

as far as I understood it is because they all use the same encryption key now and dont need any additional recovery or shared keys anymore.
