What is Wyze Watch "Phone ringing" icon for?

Happy with Wyze Watch 47 on day 2. Hopefully, a few upcoming convenience updates - BUT - what the heck is the “Phone ringing” icon for? When I tap it, it lights up, as if something has been set, but soon goes out. Is this a one-time setting or what? Can it be turned on and off, and for what? It’s paired fine with my phone, and I get Notifications of phone calls and camera Events; just confusing, since I don’t see it mentioned anywhere. Wyzegang: Any help?
P.S. While I’m griping, the ability to rearrange the group of 16 icons would be very desirable, and save lots of “swiping”.

Its a phone locater. I think. I push it and my phone rings.
