Lemmy Mods

Hello all. I received my first report as a mod, and I don't wish to take any further action in this case (it was about a post by me, in the group I created, so yeah, I'm pretty sure I'm not breaking the rules that I made 😂). Unlike my regular notifications, there's no "mark all as read" option, so how do I make that notification clear out now? I can see the report comes with a clickable tick, but I don't know what clicking on the tick does (not sure if maybe it accepts the report as valid and deletes the post? Or if it does something else?).
