Not sure what type of example you're looking for. Below is a screen of SP Pagebuilder's module function. It's extremely useful so you can utilize pagebuilder elements throughout Joomla pages via module positions (sidebar, headers, content bottom, or {load position}. We most commonly will utilize a pagebuilder module for slideshows or hero set to a full-width module position in T4. This allows not having to make the entire page full width in SCSS or utilizing page classes etc.
It's a rather powerful feature that we end up utilizing on just about every site. It'd be like having an JA ACM module that utilizes all the pagebuilder elements and layouts etc.
