Steps to reproduce

Create test groups A and B and a group folder with group A attached and B not attached
Go to the CLI of the NC installed
Try to add group B using occ with read, write, share, and delete permissions

Expected behaviour

I can add the group and the group is added to the group list. The settings in the web frontend represent the changes.

Actual behaviour

There is no description on how the permission string should be parsed in the help of the command.

Adding a user with a single permission (like write) works. As soon as two permissions are considered, the error message is

Cannot parse permission input

Server configuration

Operating system: Linux

Web server: Apache (from official docker image)

Database: MariaDB

PHP version: 8.1 (?) (from docker image)

Nextcloud version: 25.0.4

Group folders version: 13.1.1

Updated from an older Nextcloud/ownCloud or fresh install: upgraded

Where did you install Nextcloud from: Docker

Are you using external storage, if yes which one: local

Are you using encryption: no

Are you using an external user-backend, if yes which one: only internal user backend

Additional information

According to these lines, the command takes a single string parameter. However the implementation assumes the string to be an array.

My suggestion is to use some regex logic to split at all commas and spaces before iterating over the array. I can provide a PR if requested but wanted to avoid redundant work.
