Cannot complete AI/Copilot plans that require using chat

There are a few official plans by Microsoft on Copilot that, next to finishing modules, want you to:

"Explore generative AI capabilities in Microsoft Copilot, use your creativity to envision a unique destination, and craft compelling content to share its story." 

This as described above is the first milestone in three plans:

• https://learn.microsoft.com/en-us/plans/ngd7sgywpywr0q
• https://learn.microsoft.com/en-us/plans/66d5h6der787kg
• https://learn.microsoft.com/en-us/plans/m2e0fok5w6z63p

I have tried navigating to https://copilot.microsoft.com and crafting a few prompts (logged in with the same account as I'm logged in with at MS Learn), but I can't get the milestone to give me a green check mark. 

Does anyone know how to get this to completed?
