How to connect two, or more, users in the same room?

Hello everyone, how are you?
First of all, I want to thank everyone for their support.
I also want to say that I’m new to this SFU architecture and the mediasoup library, so bear with me!

Well, I cloned the project (GitHub - versatica/mediasoup-demo: mediasoup official demo application), configured the certificates using openssl, on the Mac (Monterey, with Intel chip), I even installed the certificates themselves by running “generate-dev-certificate” from package.json. I also added the variables DOMAIN and MEDIASOUP_ANNOUNCED_IP, in the server’s .env, but the first one I left commented out, and MEDIASOUP_ANNOUNCED_IP had the value 127.0.0.1. I started the server (and apparently without errors) and the app (also without errors, just a warning of a dependency on the front that will be unavailable). When I enter the url
(https://localhost:3000/?roomId=z7ln1qpx), with two different users, in two different tabs, only the video/audio of the screen user appears and not the (also) remote user. So I ask; what is really happening? Apparently, it’s as if the users weren’t in the same room…
Thank you very much in advance for everything.

MEDIASOUP_ANNOUNCED_IP need to fill in the actual communicationable ip of your machine
