Where I might be able to do this?
this is the documentation
disclaimer: not an experienced developer. Just want to receive some guidance before trying this out without breaking things. I have setup a staging enviroment aswell.
I think you’ll be more likely to get an answer if you ask a more specific question. Fewer folks are going to be interested in reading through a a tutorial you’ve linked to figure out what you are trying to do.
You mention you have set up a staging environment. That’s great. Why not just trying whatever you want to try there and see how it works?
