Correct
I think the link below is the 20 minute video by Denys Davydov, in which at the beginning he suggested this was a fight over which flag to fly over the Kremlin to celebrate the May 9 event below. At any rate the explosion apparently did little damage to the dome or the 2 men on top who may have been trying to fix the flag situation. It certainly was not big enough to have penetrated to interior rooms, much less a Putin bunker. Besides, it had already been announced he was out of town.

If this is the right video, it is followed by a long talk between a Ukraine interrogator, his Russian prisoner and ultimately his wife. After that I took a short break and left my computer running. I came back to an interesting “field trip” to Bakhmut and Ukraine soldiers doing their thing with tanks, artillery, and computer feeds. They did not seem particularly alarmed and joked a lot. [The reason This might not be the right video is because I took a laundry break, did not turn off my computer, and sometimes it jumps to other locations.]
OK, I checked, this is the right video. It plays right after a short ad.
