Hi @eliexams,
You can add the form using the “text” widget. Go to the widgets page and find the “widget box” which was created using UFW plugin and add the “text” widget to it.
In the text widget, you can add the form.
You can paste the form in both “plain HTML” or in “shortcode” format.
Save the widget and now the popup will contain the text widget with your form.
Thanks,
Aakash
