When I record Rear Cam videos the audio is full of noise and static, but audio for FCAM Videos, phone calls, voice memos, etc works fine. I want to fix this issue, but don’t know what part to buy. I think I need to buy the Audio Control/Power Button Cable (iPhone SE (1st Gen) Audio Control and Power Button Cable), but I want to confirm that the mic on this part is for the RCAM audio.

Can anyone confirm if this is the case? Thank you.

What you circled is rhe rear mic.
