[Google Analytics +] Shortcode to display Analytics graphs for multisite

Dear support team,

I have a multisite install, containing three website that each have their own Google Analytics properties : https://i.postimg.cc/SNwc8qJv/Capture.png

I've created a private page containing a few statistics pulled from the DB.

There, I'd like to add your Google Analytics + widget, parsing each website's UA and dynamically creating a link to the matching Analytics' view.

How may I do so ?

Thank you very much.
Greg
