Heart Rate tracker alternatives - do they sync to Garmin Ecosystem ?

I really want a smart wearable device such as a ring or band, that can track Heart Rate for HRV & Body Battery purposes. But I hate wearing my watch to bed, so I miss this data.

Are there any wearable devices out there from other brands that track HR, that Garmin allows to receive their data into Garmin Connect??

Or can their data be synced into another 3rd party like Samsung Health, etc, and then that data be synced into Garmin Connect? I'm hoping Samsung announces their ring in July, and that this device might work. I'd prefer a ring to a band such as Whoop, as hopefully it won't have a subscription price.

I see there is another thread about Watch tracker alternatives, which I have also posted in, and sent suggestion to Garmin.

Thanks in advance!
