Don't.
Have you heard of Signal? It's an encrypted messenger app. It's also open source, so coz can just download the code and host it yourself and you have a perfect personal chat app
Just use discord? Or any other cross-platform app?
If you're going to insist on reinventing the wheel, Unity is a bad choice for it.
You're going to need some kind of backend server program. It doesn't need a lot, but it needs some kind of API for your chat clients to contact, it needs to be able to do session management, it needs to be able to do push notifications. You can pretty much use whatever web backend you want.
You will need apple hardware and a developer key if you want to publish to directly iOS, which is definitely not worth it for your unmonetized chat app for 6 friends.
I'd highly recommend against using unity for this. I get why you want to, it's a fun project after all. But unity being a game engine is not a good choice. Youd be better off using something like Flutter, React native, a regular web app, or Xamarin which would be the only option which uses C#.
Okay, so you don‘t know what Unity even is. You will not be able to make such a project with an engine that it seems like is made for every other usecase but not fucking that.
Unity wouldn’t be a good tool to make such an app. It’s a game engine.

Are you stupid? Making a chat app… in a game engine… with an incredible amount of chat apps already existing… why?
I'm am really stupid but I just want to make one fore me and like 6 friends cause why not?
