Hello!

Sorry, I've missed your question.

By default, Messenger has ability to insert block with Messenger to any page of the site. If you like to have this ability on Profile's view page, then you just need to add new Messenger block on Persons/Organizations View page and members can see the block and join to the Video Conference. Otherwise user can create rooms/channels as Messenger's standard talk. You can create talk with participants and then start Video Conference here and all the participants will get notifications and be able to join.
