Apple Airpods Pro Issue with PUBG

Hi, I recently bought Apple Airpods Pro. While Playing Pubg the microphone on the back side over camera is picking up my audio rather than the microphone on the airpods. In the earlier 2-3 times use it was working just fine, the mic on the airpods were the receivers of my voice, but suddenly now the camera microphone is receiving the sound of my voice while playing pubg. What should I do?
