How do I get Rounded Edges on Basic Admin 2.0

What do you want to achieve?
I would like to be able to get rounded edges on the Basic Admin 2.0 UI. I have included a screenshot for reference.

Image is not mine, found from another form

What is the issue?
I’m unsure how to do this as scripting is not my profession.

What solutions have you tried so far?
I have looked all over DevForum and multiple other websites. I have looked all over the Essentials Client and can’t figure it out. I also looked all over the I have found solutions but they are not as specific.

Use UICorners. You can change the radius of the corners too.

Use the UICorner child, or you can use a plugin called Roundify however, I wouldn’t recommend it since it uses an Image to create rounded corners.

Use UiCorner. It’s the best way to do it. I wouldn’t recommend you use Roundify but if you have something else to do with it then definitely use it.

Where do I put it though? I have no prior knowledge of working with GUI’s so this is all new to me.

Parent UICorner to any UI you want to give round corners to
