How can the data source in this Apple mobile phone health be changed to WeChat?

The meaning of this picture is not that the data comes from QQ, but that QQ requests the data in IPhone to be used in QQ. That is to say, if you want to display WeChat on it, you can jump to Health WeChat when you need WeChat to use health data.

Specific operation:

Open WeChat, click Search, and search for WeChat campaign.

Open the WeChat activity and click Settings at the top right.

Locate the data source and click authorize.

I have authorized it here. Just click in and follow the instructions.
