Asking for Names in Embeddable Signup Forms

I created an embeddable signup form. However, it only asks for the email. I would like to get the user’s name as well.

How can I add an input field for “Name” in the embeddable signup forms?

I was asking myself the same thing yesterday. I think it’s not possible as of now, because it’s just a single field signup, it overrides also the main portal settings if you toggle the name on it.
