right-click doesn't do what it is supposed to, or rather the message is wrong probably

I just installed Greenshot.
Now I have a notification in the Windows 10 notification sidebar shown in the screenshot.
It says "Click here with right mouse button or press print key".
But if I do as suggested (clicking with right mouse button), only the windows context menu for notifications opens like also shown in the screenshot.
I guess this context menu is application supplied in older windows versions or something like that and now the message is just wrong.
