MacBook Pro 16'' Rattling noise when tapping on trackpad

See the recorded video. Regular clicking sounds right, but tapping on the trackpad has this rattling noise from the bottom of the trackpad. It almost fell like there is a loosing spring or screw somewhere in the trackpad and made the entire bottom case sound like a drum.

Didn't encounter such issue in all my previous Macs (2015 MacBook Pro 13", 2018/19 MacBook Pro 15"), as well as the other 2023 MacBook Pro 14". All of those are very rigid when tapping the trackpad.

This is my second MacBook Pro 16'', the first one has clicking and popping sound every time running something requires high power, and top case doesn't align with the bottom case. I returned that one and get this one, which resolved all those issues except the trackpad is making this very distracting noise.

Any suggestions? Not sure if that's a one-off QC issue.
