How do I define the type of data to grab?

I’m able to use this plugin to pull in the post information from the site I want to, but how do I choose a different type of data? I’ve not been able to pull in anything at all from it. I tried type=”page” and type=”pages” but it still only returns the posts. I’m actually trying to pull data from a custom post type, I successfully registered with the REST-API and can see when pulling a types request in PostMan, but I can’t get anything but posts to display from this.
