Unknown invisible icon in menu bar
I've been noticing an invisible icon in my menu bar & I'd like to find what it is.
Clicking on the icon gives a shadow, and Command+Drag allows me to move it in between other items or throw it out, but I don't want that since I need to know what it is to remove it. Also, right clicking on it does nothing.
I tried the solution in this Apple Support ticket (Unknown Icon in Menu Bar - Apple Community) , but it only showed Siri (which is unhelpful).
I was wondering if there's a way to know what it is and delete the app, since it can be harmful/malicious.
Thanks.
