JPLAY ? Qobuz iPhone

Do I need the Jplay app to stream hi resolution from iPhone qobuz to a Hegel H190. The Qobuz app won’t do it by itself? A lot of confusing articles and posts.

I don’t want to purchase Jplay if it is not needed.

Hegel page about streaming mentions Qobuz only in its UPnP section and says to use Jplay.

I see wired solutions but I need to control the system from another room.  I could use the iphone to control a PC that is wired via USB but would prefer to just open an app on my phone and play music at hi resolution to the Hegel.
