Polly .Net shut down application gracefully with IHostApplicationLifetime

The end outcome is to shut down the application if a specific type of exception (DatabaseException) has occurred.

However the current method HandleDatabaseException does not stop the application, the execution will carry on. Even though the _applicationLifetime.Stop() is executed.

private IHostApplicationLifetime _applicationLifetime;

public void CreatePolcy() 
{
    var policy = Policy
                .Handle<DatabaseException>(ex => HandleDatabaseException(ex))
                .WaitAndRetryForever(
                    retryAttempt => TimeSpan.FromSeconds(Math.Pow(2, retryAttempt)),
                    (exception, timespan) => HandleRetry(exception, timespan, stoppingToken));
}

public bool HandleDatabaseException(Exception ex) 
{
   _applicationLifetime.Stop();

   return true;
}
