Hello, I am trying to set up a sign up page where users enter their email addresses in order to be updated with info about the apps progress. I have a textfield and a a checkbox group on the page and id like to use both in order to populate a collection on the backend. I have an arrow button that I wanted to use to send the emails to the backend and then navigate to a confirmation page. I was hoping someone here had any insight on how id set up the actions because its not creating a document when in preview mode.
