Hi, I am new to web studio and have the following queries. Please respond to them:

1) Is multi-level access control available for my project in Web studio?
2) I am willing to self-host the Web studio site. As per the documentation, the site should be accessible via my custom domain mapped on my server. However, I need to know if it will still be visible at the URL created on Web studio as well. If yes, can I have a private workspace?
3) There is publish limitations as well, if using pro plan could solve this?
