How do I enable SSL via snap installation?

Hello,
i installed nextcloud on raspbian via snap.
But I can’t:

  • Understanding how to enable SSL (HTTPS), I tried using through shell << nextcloud.enable-https lets-encrypt >> but it returns “command not found”.

  • How to change the storage path for a user, (I want to use the USB sticks connected instead of the raspberry flash memory).

I trust in your help, thank you very much!

Sorry i do not use Snap. Please post fully commands and errors with Cut-and-Paste if possible.
Perhaps you missed only “sudo”.

sudo nextcloud.enable-https lets-encrypt

It’s returned to me: sudo: nextcloud.enable-https: command not found
Thanks for reply!
