Video screenshots on Android

I’m running Zwift on an Apple TV box and use the Companion app on Android for control and also as a bridge to connect. I have been seeing people posting Video screenshots but I don’t see to have the button icon for it on either the AppleTV (a TV) or on my phone in the companion app. Has this feature been added for these devices?

Which model Apple TV is it? I’m guessing it’s the first-gen 4K, which currently doesn’t support video screenshots (only the gen2 and gen3 4K).
