Need live video chat in WordPress website

Pre-Sale Question:
Well, I have a WordPress website https://scriptube.org/

where people can upload videos in my website.

I am using streamtube theme

People/Host can create rooms, start an event.
Other People can scroll down and see live people , live rooms , events.
Other people can join them .
They can talk to each other.
They can interreact each other , can see each other through vide chat.

All that happens in video chat rooms like Instagram Live , FB live.

Is this possible with your free or pro plugin? I am Okay to pay you any price as I know this is a big feature.

If you have any demo with this functionality please share it with me.

And do you provide live chat support after I purchase your plugin to setup the plugin precisely ?

Looking forward a positive response from you.
Thank you!!!!
