Google OAuth does not return to Median app after Chrome Custom Tab authentication (Android App Links / assetlinks.json)

Hi,

I'm using a Median-built Android APK with Google OAuth (NextAuth).

My app package name is:

co.median.android.eezeemo

Android App Links are enabled in appConfig, but my OAuth flow opens in a Chrome Custom Tab and does not return to the app after authentication.

I need to configure Digital Asset Links.

Could you please provide:

the SHA-256 signing certificate fingerprint for my release APK,
whether I should host my own /.well-known/assetlinks.json,
or whether Median generates/manages this automatically.

My callback URL is:
