iPhone 15 Pro Screen Popping Sounds

I don't know if it's from the phone's taptic engine, but when I press a little harder than usual, the lower part of the display makes a very slight clicking sound, I'd say. If you put it close to your ear you would hear it a little better. I don't see any faults with the display and the way it is glued and I never dropped my phone. I don't know if this is a cause for concern .🤷‍♂️🤷‍♂️ I contacted with apple who told me that this is nothing to worry about, but if I look for this sound I will find it. Do you have that slight sound when your screen is off?
