Sandbox Feature

I have created a complete form and put some effort to customize the form as I wanted. Pretty much 90% of it is paid, but still, I was going to use the free customizations. The real problem is that if you don't pay, your form is completely unprotected. It's impossible to create a form just for me to create tasks in my databases at Notion. You may call this section sandbox, because the the only purpose is to play with the tool and waste time.
