How do you round the edges of a layout?

Hello. I'd like to round the corners of horizontal or vertical layouts like the title, is there a way? I downloaded MakeViewUp, but I'm not sure how to do it. Can you tell me how?

What about Play Protect? I used this extension but play protect blocked the instalation

Nothing to do with extension, select "Install anyway"
