It's a brand new "Cube Attain SLX", aluminium frame and carbon fork. Only taken on one short trip and did not notice this while riding outside. Now I have detached the rear wheel and put the bike on a "Van Rysel D100" smart trainer. The trainer is using the same exact model of cassette, haven't regulated the derailleur, which could probably improve shifting but does it have anything to do with the vibration? It can be felt better on the smaller chainrings, especially when accelerating, putting out power or in high speed.
It goes through my pedals all the way to the seat and cockpit. Perhaps it's more noticeable on the trainer, and i just didn't note it while riding outside? Maybe it occurred later on the trainer itself? Should I try regulating something, could more lube help? Thanks!
Chain vibration, felt through pedals and rest of the bike.

Not sure if it becomes really clear from the video. It seems to me that it’s the chain that is vibrating more than it should. Chain is routed correctly? Can’t be a problem with the BB, right, not on a new bike?
Bit of a newbie myself so take this with a grain of salt:
I know when setting up on my Kickr Core I had a similar issue. The cassette / chain was near enough to dead quiet on the bike but was loud / grindy on the Core.
Essentially I figured out that the cassette spacer offset wasn’t big enough. Factory manual specced it at 0.8mm as provided. With one MTB I had it was more like 1.2mm. On my current road bike it’s more like 1mm.
Obviously you can see hesitation in the shifting but it might not be the derailleur. I’d start with moving the cassette back / forward along the hub and see what you get.
