Xfinity Stream App for access on the PS4/PS5

Hello! Wondering when Xfinity will add the Xfinity Stream app to the Playstation Network for download? Every other Streaming App is accessible and you are able to download to use on the PS4/PS5 EXCEPT the Xfinity Stream app. WHY is this? Why can't we access our DVR recordings and TV from the Playstation? And when will this be resolved or possible? Hopefully SOON?
