Emitting and collecting on a SharedFlow to answer on a Reddit thread: https://www.reddit.com/r/androiddev/comments/tirxqq/help_with_auth0/

AuthCredentialsManager.kt

// Add into class AuthCredentialsManager
private val mutableCredentialsFlow = MutableSharedFlow<Credentials>()
val credentialsFlow = mutableCredentialsFlow.asSharedFlow()

suspend fun emitCredentials(credentials: Credentials) {
    mutableCredentialsFlow.emit(credentials)
}

fun getCredentials() {
    manager.getCredentials(object : Callback<Credentials, CredentialsManagerException> {
        override fun onFailure(exception: CredentialsManagerException) {
            // Error
        }
        override fun onSuccess(credentials: Credentials) {
            // Use here your coroutine scope
            coroutineScope.launch {
                emitCredentials(credentials)
            }
        }
    })
}

RandomObserver.kt

// Place this where you want to collect from the flow
// Use here your coroutine scope (use viewModelScope if collecting from a ViewModel)
coroutineScope.launch {
    // Collect from the flow
    credentialsManager.credentialsFlow.collect {
        // Do whatever needed with the credentials
        println("New credentials received: $it")
    }
}
