How can I do custom auth with the latest version of moralis and react-moralis on an expo app

I want to use these version

moralis -> 1.8.0
react-moralis -> 1.4.0
expo -> ~45.0.0
react-native: 0.68.2

I will not use walletconnect for auth.

A git repo will help me or any suggestion/instruction would also be okay.

By custom auth do you mean custom connectors?
