How to Use the Matter Web App on the Mac

Matter can be run as an app on the Mac. And this is the Read Later client, not Matter the home standard,. It's the Read Later app. I use it primarily on my iPhone and iPads, but I do a lot of saving of articles on theMac. Sometimes when we're getting ready to put out the newsletter for Club Mac Stories, sometimes I'll have stuff in there that I know I wanna grab a link from - so I'll open it there. So tell me, how do you use the Matter web app?
