Question How to code a local Android multiplayer using WiFi hotspot?

Hello, everyone.

I know there have been many posts about this topic the past, but since things have changed, I believe it's a valid question.

How would I go about creating a local multiplayer system for Android games that uses a WiFi hotspot to connect the players? Where do I start to learn about how to make such a system?

I have some experience with c# and unity, but not specific experience with networking, so I'd love to be pointed in the right direction to get this local multiplayer system running sooner than just learning about networking in general.
