KWatchGnuPG pops up - why and what for?

Running on KDE desktop and trying to learn enough about encryption to use Enigmail, Mailvelope and NitroKey Storage. Still very low down on learning curve and am only working on Enigmail at present but after logging out and back in after an update recently a pop up window opens with KWatchGnuPG. Why and what for and should I close or just minimise?

I have not run into KWatchGnuPG. So I did a google search, and there is a web page for it. It seems to watch for logs.

Presumably, it saw a log entry that needed human checking.
