Jitsi how to start a session with predefined password

Hi Ive found client is so good there is no need to set up my own server BUT…
Mostly, we start sessions like this : https://meet.jit.si/mygroup
As I develop my site further and if the security need arises it would be great if I could instantiate the meet similar to:
https://meet.jit.si/mygroup/pwd=1234 meaning the group is initialized with a password of 1234, and I could send the same link to authorized persons to auto-login.

Is there such a thing currently or similar to? Sorry but I cant find any reference to it here if there is.
