Waiver for yoga class

[nitadiaz]

I'm teaching online yoga classes via Zoom. Attendees register via the Zoom registration link with their name + email address and automatically receive the link to join the class.

I would like to include the option for registrants to say whether they have signed an electronic waiver or not (maybe a checkbox?) and then add the waiver link for them to sign. Can I add additional fields to the registration process so I can keep track of who has signed the waiver and who hasn't?
