I have great news on this! You'll find control around this feature on the 3rd step of the Widget creation (or edit) screen.
Once you're in there, look for the Widget Settings section. Select which pages of your website you want your pop-up to show. If you can't find the page in the dropdown, you can select a Specific URL where you want to show the pop-up. Just remember that when choosing this option, start your URL with https:// and use your complete URL.
In addition to selecting where you want to show, you can also choose when you want it to show. If you select the option Once every period of time, you're gonna have to input the number of Days/Hours/Mins you want to show your pop-up reminders.
If you still have questions, you may submit a ticket here and we will get back to you as soon as we can.
