Content manager on steam link

I'm not sure if it's possible but I want to ask just incase it is.

I am trying to play via steam link from my main pc to my MacBook. I have my ps5 controller connected but it is not being recognised on content manager when going to settings. The game itself loads up fine when clicking drive and I have also enabled steam input for PS controllers. Is there a work around for this or is it just impossible to do so?
