deviceSettings.tonesOn for devices without tones

Hi,

I have a watchface and I would like to show an icon when the tones are off, so I use "deviceSettings.tonesOn" to know if tones are off or on, the problem is that for devices without tones, as the vivoactive 4, is returning false, but I don't want to show the "no tones icon" on devices without tones. Is there other api function that I could use to know which devices allow tones and which don't.?

If there is no way to know this I think that "deviceSettings.tonesOn" should return true when tones are on, false when off and null for devices without tones.

Thanks
