Can I make My Replits on my account private (so students cant see them)

I’m a teacher looking to make my own Replit’s private (students have looked up and found my account). I want my Replit’s private so can create my own solutions, build assignments, and do any other programming work, without students seeing my Replits.
Is this not a basic feature? Do I need to pay for this?
Thanks for your help,

Private repls are paid on a personal account. But if you use teams for EDU you can make a project but not publish it so you can work on it without your students being able to see it.

I have set up a Teams for EDU account, but I noted that I couldn’t create projects for Pygame…where as I can create Replits that have Pygame this true?
