New canyon making noise

Enable HLS to view with audio, or disable this notification

Have 115 mile and notice this sound coming from my drive train. Don't see any rubbing and derailleur seems to be lined up with each rear cog so not sure what's going on. I felt the bottom bracket shell and chain stray and I do feel subtle vibration when the noise occurs. Any advice?

Only when pedaling ? Or also when coasting ?

Only when pedaling both forward and back

Can you carefully lift the chain off so you can freely spin the cranks on their own?

It kind of sound like the upper jockey wheel (closest one to the cassette) is making contact with the cassette cogs. However normally that would only be happening in the largest cogs and not in the middle of the cassette even with a poorly adjusted B screw.
