nRF5340 Audio: wanting to play music from a phone device

Hello,

I'm a little new to this, so sorry if I'm not asking the right questions. I want to be able to connect my phone to my nRF5340 to use as headset with Bluetooth (using this project as a guide: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/applications/nrf5340_audio/README.html#i2s-based-firmware-for-gateway-and-headsets). However, when I pair with a phone (an iPhone in my case), the phone does not seem to recognize it as an audio sink.

It advertises Audio Stream Control and Published Audio Capabilities as services.

Question 1: Are these services enough to receive audio from the phone?

Question 2: I'm assuming services are all I need to know in order to pair and receive audio from my phone, is this true?
