Now, you just need to configure your visibility settings (where your form is shown).
Select the categories, posts, or wherever you want your form to be shown.
You can also configure the triggers of when your form should be shown (i.e on Click, % scrolled, etc.)
Once you have completed all the previous steps, click Publish and you should be good to go.
If you want to test to see if your pop up is working correctly, head over to the selected part of your website in a new incognito tab (or private search, where you are not logged in), then see if the form appears on your trigger.
