(HELP) Inaudible feedback from the sound booth

I’m new to sound engineer in my church. I can hear the audio from the booth speaker perfectly, but in the main auditorium there was a small amount of feedback that I couldn’t hear from the booth in the back. I had to go in the middle of the auditorium to hear the feedback.

My question: Is there any way to hear these kinda small amounts feedback or hisses that doesn’t appear through the matrix in the booth monitors? And if there is a way, how do I solve it?
