Can't embed TELUS TV+ in an iFrame

When I try to embed TELUS TV+ in an iFrame on a webpage with the URL https://telustvplus.com/#/player/live/?stationId=58 and then access it from Chrome, I'm able to access the site in the iFrame and login, but then when I try to open up the Live TV stream I get a "browser not supported" error. 

On the same browser, when I access the same TELUS TV+ Live TV stream directly using URL https://telustvplus.com/#/player/live/?stationId=58, it plays just fine.

Is there some kind of restriction from running TELUS TV+ in an iFrame?
