Database or Server to host a group of users?

Hey I wanna make an app where I am able to have users create a room and invite other users using some invite link or room code I was wondering if anyone can give me pointers on how to do this?

An example of my UI is below. Creating the UI shouldnt be too hard its just trying to find how to group users together.

Building an app is like building a web app, you share data with the server and store all of it on a database which is on the same server as your API.

Unless you wanna use a server less solution, my best bet for a server less solution would be Firebase, if you are down for an API based approach, then build an API using Express, Django, whatever, and use MySQL, PostgreSQL, Cassandra for your database.

To get started with APIs, you can go here: https://www.youtube.com/watch?v=-MTSQjw5DrM

Not my channel, Fireship also has tutorials for mobile apps, firebase, etc.
