Pop-up window after providing email

I need an option, that after providing an email, hitting submit and seeing a success message - a pop-up window appears that carries a survey with additional optional questions.

Does please anybody know how to do this?

Hi Juraj @Juraj_Vojnik, welcome to the Webflow community!

Does it necessarily need to be a pop-up window on the same page? You could easily do this by redirecting to a specific page and showing a new form with additional questions.
