iPad Air M3 makes random clicking sound

I’ve got an iPad air m3 a month ago and I immediately noticed it randomly makes a "clicking" sound when I use it. After 2 weeks I went to an authorized service point and left it there for further investigation and after another 2 weeks (yesterday) they gave it back and said the tests they’d run didn’t confirm such problem occurs. I managed to record it yesterday (I didn’t have the video when I went to the service point because, as I said, it happens randomly). It’s my first iPad, is it normal for the device or this exact model? Link to the video I posted on Reddit: https://www.reddit.com/r/ipad/s/7wvpUf6YxC
