Social login not redirecting when using Custom API

Hello! My mobile developer is experiencing a blank white screen when the user login using a social connection (Google/Facebook) when using the audience of Custom API that I made. But when he changes the audience to Auth0 Management API it will work. My audience of custom API also works on passwordless connection. What do we need to do?
By the way, mobile devs are using react native and backend devs are using NestJs.
