Xfinity App on PC?

Too much confusion over the past couple of years about servicing our accounts, especially recently with Peacock and Wi-Fi.  I don't want to use Xfinity App on my phone, nor should I have to, and don't use the Flex box.  I want to do it on my PC just as I always have done.  But now I cannot, and I get the message "The My Account app is going away soon. Now, the Xfinity app is the best way to manage all your Xfinity services."  The problem is that it is only for crapple iOS or Android!  No Windows (for my PC).  What gives?  I guess Comcast thinks they can force people to use a smart phone or one of their Flex boxes to manage their accounts now?  WTH?!?!?!  Help!!!!  Thanks!
