Based on my limited knowledge, there are two or three ways you could accomplish that. The first two ways are through Roon and Audirvana. Both support Qobuz and have remote app that allow one control playback on PC / Mac from a tablet or phone. The thrid way is through JRiver. Since JRiver does have native Qobuz integration, you need to work around it but you could control the playback via its JRemote. These options are not free as you know.
Lastly, if you could set up a PC/Mac as a UPnP/DLNA control point, you can use apps such as BubbleUPnP, mconnect, or Foobar2000 to control playback. Some servers might be free, but I’m not sure how to pursue and accomplish it. I tried Foobar2000 once but failed. It’s not worth my time now since I have a pretty good streamer.
