North Korea Expected to Cause Small Level Provocation Before Biden-Moon Summit
North Korea tends to slowly build up towards a provocation cycle, so I would be surprised if they did anything bigger than what analysts are expecting:

Experts said Pyongyang may attempt to rattle its neighbors and the U.S. with a number of low-profile provocations before the May 21 summit between Biden and South Korean President Moon Jae-in. These could involve the closure of North Korea’s own organization on inter-Korean relations or the launch of short-range missiles. (….)
Cheong said Pyongyang is expected to limit its level of provocation given the relatively moderate expressions in the statement from the North’s foreign ministry director. According to him, Kwon, who is known as a hardliner, has toned down his rhetoric by indirectly mentioning Biden as the “U.S. chief authority” and described the president’s remarks as “a blunder,” not a provocation.
