Wix events: customize registration form based on users

Hi there,
I would like to have 2 registration forms to my event or be able to hide a question from the form based on the user logged. How should I do?

My use case is I would like to invite some guests to a brunch the day after my wedding party so I want to ask them who will come without everyone knowing we have a brunch the day after.

I tried to dig into the the form with the wix api but I didn’t find where I can find the registration forms.

Thanks for your help.
Frederic
