AirPlay'ing to AppleTV doesn't disable auto standby

When I cast Corrd music from my iPhone to an Apple TV 4K via AirPlay it seems that Apple TV’s auto standby (15 minutes by default) is not disabled. And after 15 minutes of playback without interaction with Apple TV, the standby kicks in, and I can’t listen to music from Corrd for a prolonged period of time.

I should either increase the standby time in Apple TV settings, or manually override standby timer in Apple TV, or, use Apple TV remote periodically.

Is it possible for Corrd app to disable Apple TV standby while playing via AirPlay?
