MuSo 2 and HDMI settings

I had to do a factory reset on my MuSo this week. That included an HDMI connection to my TV. As I recall from my initial setup, there was a way to control how the MuSo responded (or didn’t) when the TV was turned on. Most of the time I don’t want to use the MuSo as my soundbar - only when I am watching a program with a musical component (like the opera I am planning to watch tonight). But I can’t find that setting. And right now, the MuSo turns on every time I turn on the TV (and works!). And I no longer have an HDMI “button” on the app. Nor do I have an option to add one in settings.

Never mind - another Muso reset and the HDMI button came back.
