When you need to make an external link stand out within your lesson. Try a button!
Simply drag the button lesson item to your lesson builder, configure what it says (call to action), and where it goes (URL).
The most common example is the LEARN MORE button - which takes learners to an informative web page to learn more.
Copy your web page link (URL) and paste it into your button configuration, decide what your Call to Action should be (Learn More, More Information, Click Here) then click Done Editing to add it to your lesson.
