Trigger: how to

Hi,

I’m trying to setup a popup that will open on click but my installation does not show the “Trigger” box is shown in this doc https://docs.wppopupmaker.com/article/144-trigger-click-open

In fact the “Popup settings” box is totally empty.

I’m running the latest version with the latest version of WordPress with a Divi theme.

Thnaks for help.
