Files_external:create and all Option

Hello, everyone!
How can I use files_external:create to add an SMB share with occ? Basically, you can do it with the following command.

sudo -u www-data php /data/webserver/www/nextcloud/occ files_external:create Philip smb password::password -c host=192.168.x.xx -c share=profiles -c user=philip -c password=wm2026

But I’m missing the “Restrict to” option.

Where can I find a list of all options and their parameters?

Thanks
Philip
