Get rid of app that shows pink column guides

I downloaded a free app to help me with guides in my Wix Studio Editor and I would like to get rid of it. It just shows pink columns on my editor which are of no use at all.

Unfortunately, I do not remember the name of the app, and nothing comes up when I click 0n My Business icon in the left hand column.

Does anyone have a similar problem and could let me know how I can get rid of it?

The Pink columns are Design Guidlines. Here is how add and remove them
