Galaxy Fit2 watch and iPhone compatibility

I recently bought the Galaxy Fit2 but I'm unable to use it with my iPhone 10s. The Galaxy wearables and Samsung Health app work fine but it's not pulling info through to my Health App.

I am trying to add it as a data source in my Health app but I can't locate the device/app... Please help!!

Is it supported?

I am on iOS 14.3 and my watch is on the latest firmware.
