Hi there, Trish. Welcome to the community!
There's a couple of options for you. If you need the user to navigate to the page, you can add a button on the slide and add a hyperlink to that button (on click). You could also add an "Exit Course" trigger to that button. So, it should exit the course and take the learners to the page you wish to show them (the Moodle page, or any other).
Here's a quick example
In the example above, clicking on the button closes the course and opens a browser window for this thread.
Here's how I set it up:
Now you can modify some of the options when you add the URL and Jump to trigger, if you'd like, as well.
Let me know if you have any questions
