Reverse Proxy with jitsi meet and Docker

Hi I was able to setup Jitsi meet with docker on local network and if I type my ip address and port everything works fine.

But I wanted to set a custom domain to it, like meet.example.com. I saw it can be done via reverse proxy. But I am completely new to this and have no idea how nginx works or how I can integrate with Docker.

If someone could help it would be a great help
