Hello! I would like Garmin Connect and my Phoenix 6 to have the YouTube Music app. Thank you
GitHub - sigma67/ytmusicapi: Unofficial API for YouTube Music
Not native, only in Python.
I have a feeling that they have a closed (to the public) one though, otherwise how would Sonos be able to access YTM? And countless other devices out there.
Should contact Google/YouTube and find out. I mean, Garmin is only the single largest smart-watch manufacturer, I'm sure they'd listen.
