Confused on what code to use

When I look at your example code it doesn't match the descriptive text.
What I'd like to do is automatically add to project "https://github.com/orgs/Bearsampp/projects/2" if the "bug" label has been applied, into the "Todo" column and then when a pr is created move it to the "Needs Review" and finally when merged move it to the "Done" column.
How do I implement this?

Thanks in advance
