I was having a heck of a time figuring out how to get the help suite working (after I found out it exists). Check out the links below if you want to install the text suite function on your codepen projects.
Here is the link to the pen by freecodecamp to install it in your html code: https://codepen.io/freeCodeCamp/pen/MJjpwO
And here is a link to a youtube video I made on how to get it working: https://youtu.be/_i7wgVpg4Bo
I hope this is helpful for somebody. The test suite is a really helpful feature.
