How to know if Duel Mass Flywheel is failing?

Car makes a slight chatter when going from 1st to 2nd and 2nd to 3rd as the clutch is being engaged and the throttle is being depressed once and a while. I can only hear it with the windows down, with them up I hear zero noise. I let the engine idle and there's no noise, I moved the clutch very slowly in and out and tried to hold it where I thought the bite point might be in a few different spots and didn't hear any noise. I know duel mass flywheels are notorious for going especially in these cars, what's the proper way to diagnose it?

Added a video for diagnosis

You can hear me starting the vehicle, shutting it off with the clutch engaged, then shutting it off with the clutch disengaged and also a little where I'm pushing the clutch in and out.

The difference will be clear, clutched disengaged is much quieter I just don't know if it's normal noise or Dual mass flywheel noise.

Note: You can hear the noise from the second video as I let the clutch out after the first start in the first video.

Here is another video filmed near the clutch so you can hear the chatter as I engage the cluth then hear it quiet down as I disengage. Its a little hard to hear after the first engagement but it's still there. sounds like a fast clunking.

I have a '15 with 83k miles on the odometer and it's made that noise since day one.

I have a '17 with 13k miles on the odometer and it's made that noise since day one.

I think it's just the nature of the beast.
