Open paywalled link in Apple News+ on pre-Big Sur Safari?

Hey, all. I fairly recently learned that for certain paywalled publications that are included in Apple News+ (New Yorker and WSJ, on iOS you can use the Share Sheet from Safari to open a paywalled article in the News app.

At least on Mojave, there is no corresponding Safari sharing extension. (I understand there is on Big Sur, but I’m not there yet.)

Anyone have a Keyboard Maestro macro, bookmarket, or similar to pass a paywalled URL to Apple News in order to view it there?
