How to know the latitude and longitude by T-beam?

Hello, I am a new user in T-Beam-Meshtastic v1.1

I have some question want to ask.

  1. How to get the database

  2. T-beam can support me to do any further development? E.g. create new app for fun

  3. In not use the app, When communicating with other members, how to know the latitude and longitude by T-beam? I just can see the distance by T-beam.

Thanks for your help!
