Help understanding basic site plan and workspaces

So if I have a freelancer workspace plan and I make a site and transfer it to a client and they publish it and get the basic site plan. If they invite me to their free workspace would I be able to still edit the site after they published it? I read that if you get the basic site plan only 1 person can edit the site. So since it’s in the client’s workspace are they the editor or can I be the editor, how does that work?
