Using Razer Audio Mixer to connect Smartphone with PC

Dear Razers, I would like to play with my friends on PC and (due to crossplay) talk with them in PS4/5 Partychat. As it is right now I just connect a in-ear Headphone with the smartphone and put my over-ear headset over it. Not really a suitable solution. Would it be possible to connect the smartphone with a cable to the razer audio mixer and forward the signal from the smarthpone app to my headset and back from headset to the smartphone app? Maybe somebody has already a setup which answers/solves my question/issue? Regards,
