Xfinity App Unavailable on TCL Google TV

I just purchased a brand new TCL 75QM7K TV.  While setting it up, I discovered that the Xfinity Streaming App is not available on Google TVs....  WHY???!!!!  This is unacceptable.  The Xfinity Streaming App should be available on all TVs as all other apps like Netflix, HBOMax, Prime Video, Disney+ are.  If they are available, so should the Xfinity Streaming App.  The workaround is to cast the Xfinity Streaming app from my phone which is ridiculous!  I have been an Xfinity customer for many years and have spent tons of money on your services.  Xfinity needs to fix this ASAP, I know I am not alone with my frustration on this issue.  I would like to know why this app is missing and what Xfinity is doing about it.
