Peugeot 206 diesel engine and chassis shaking at idle

Hi alaikum, the engine was vibrating when I opened the hood. I took it to industry. Engine mounts changed. I turned the ignition on the way to buy from the industry and the inside of the vehicle vibrates like a minibus. The moment I move is completely gone. But the moment the car stops at idle, it shakes so much that the windows vibrate. The engine still vibrates. What could be the reason even though the engine mounts have been changed? The master says that if there is a problem with the chassis, if the vehicle has a previous accident, it may be because of it, but does the vehicle in the air on the lift vibrate like that? Like I said, it vibrates like old vans when stationary. The old ear they replaced was severed, almost not trembling like that back then. We went because the engine was shaking, the ears were changed, the vibration in the engine did not go away, and the chassis began to vibrate. Now, why might he have done it when he put on new ears?

Whispering while idling and when you touch the gas, neither the engine nor the chassis vibrates. I added a YouTube link.
