How to transfer Samsung Health to Apple Health

How do I get health data from my Samsung Gear S3 watch to be a data source for my Apple Health app?

An earlier thread suggested that when you installed the Galaxy Watch Sx app to simply allow Samsung health data to be written to Apple Health during setup.

I’ve installed, deleted and reinstalled the Galaxy S app twice now and there is no place in setup to allow or select this. Is there a different fix for it?

thanks.
