Prevent banner ads from breaking scaling

I added a bottom banner to my game following the guide on GDevelop’s website, now I tested it but once it loads, the game gets scaled down by a little which I wasn’t expecting and it adds a little margin on the right side, is there any way I can avoid this?

My workaround for now is centering the camera on the X axis, this makes the margin at least split and be symmetric on both sides
