Cannot locate "Apple Music Classical" in the App Store on Mac in order to download it -- HELP!

Searching the App Store for "Apple Music Classical" or even "Apple Music" produces lots of music apps for Apple Macs but doesn't make it possible to narrow it down. I want the one developed by Apple as a free add-on to "Apple Music". Free? Have spent a lot of time searching for it unsuccessfully. At this point would be happy to pay just to locate it. Any ideas when the search bar produces hundreds of items generally related to music on Apple but not the one with a specific name "Apple Music Classical"? Thanks in advance if you can bail me out. :)
