When I attempt to get authorization token I get 400 error. I pass in the following info: client id team id key identifier client secret access code redirect url I'm testing this on a launched nodejs backend, and a testflight build of my react native/expo app. I know my code works because I'm using the exact same setup on a different project and it works perfectly. I'm assuming I'm doing something wrong setting up the keys in apples Certificates, Identifiers & Profiles site, but anything I try doesn't work. Is there clear instructions somewhere on how this should be set up?
