which were confirmed by the action in the form of shelling. Lol.

Shelling with what?
Confirmed by what sources? Russian? AFAIK there are even reports from seismic watchers in Norway that there was an explosion at the dam, not shelling. US satellites confirmed the information with infrared sensors that detected a single explosion.
Also, according to reports from Ukraine the dam was rigged with explosives some time ago, long before the counteroffensive. This is consistent with the way Russians operate. They did the same in Zaporizhzhia power plant and almost blew it up when one of their mines exploded unintentionally near one of the buildings.
