How to launch "New Update" window again?

Hi! I’ve updated Plasma to 6.5.90 through pacman right now and a new window popped telling me about it, but I dismissed it so I could reboot the system. After rebooting, only Welcome Center showed up, but not the “New Update” window. How can I launch it again, so I could look for new features?

dunno.

but here are the release notes
