[4.7.0] Add user to room on "Click to Join!" button press

[artlive89]

Description:

Fix #19420

Steps to reproduce:

1. Start a new Jitsi call in a channel or discussion (logged in as a member of the room). Then, access the room as another user and press the "Click to Join!" button. Expected behavior: the user should join the room (if they're not already a member).
2. Access a discussion inside a channel (public room). Expected behavior: If the user is not a member of the discussion, a "Join" button should be displayed in the message box.

Expected behavior:

Clicking the button should open the video.

Actual behavior:

I click the button and nothing happens.
