Cameras appear in Roku media player but won't open

My Roku TV is integrated into HA.

In its media player entity in HA, I can “browse media” and select apps, cameras, etc.

My cameras (Frigate) appear in the cameras folder but when I press any of the cameras, the feed doesn’t open on the Roku. The apps open just fine though.

Is there something additional I need to do to be able to open those on the Roku via the media player? I can’t find any guides online about it.
