What is the correct way to replace rgba in rgb with regex?

Question

Regular Expressions

Greetings, there is a need to replace a lot of occurrences of the type rgba(168, 210, 100, 1) in a text document with rgb(168, 210, 100) . The values ​​are always different, the opacity is not necessarily 1 - in short, you need to cut off the letter a and the last semicolon before it.
I think it should be easy with notepad++, but I rarely come across regular expressions, so it's even stuck ...
