Addon Form Builder and email notify extra fields to Admin on User registration

Hello

I am wanting to
a) Have a user self-register for a free membership
b) In the registration form page I want to have extra fields , for example where the User can enter text in a Further Information text area field – I see I can do this with the paid AddOn Form Builder

c) I then want that WP Admin is email notified when the user submits the registration (Checkbox “Send Notification to Admin” in Email Settings), but in the email is this Further Information text, as well as the normal username and email address fields

Does the Form Builder do all this ? Where does all the additional fields go ? What are the new tags {abc} etc Especially – Is the content of the extra / custom fields passed in the email notification to WP Admin. Without this its not very useful for me

I looked in https://simple-membership-plugin.com/simple-membership-form-builder-addon/ but did not see anything … or maybe I missed it Or is there a ‘try before buy’ for the Foprm Builder addon
