Upload Apple health data to MyChart

I successfully linked my Apple Health on my iPhone 11 PRO to my Providence MyChart system (as well as the UCLA, and Maine Health etc.) I can see years' worth of my medical data from these sites on my iWatch 7, and my phone. My primary healthcare doctor would like to see my Apple Health information (my EKG's, HR, Oxygen/Blood numbers recorded from my iWatch. The Apple app says my doctor needs to approve data transfer in that direction. This makes no sense. AND, my doctor, and the MyChart IT team, have no idea how to do it. Please help.
