I'll write tests for the new intent.

Looks good to me! Were you able to test this manually by any chance?

Nope, I'm new to Alexa skill development and didn't want to expend the time and energy to setup things for manual testing. And it's hopefully too simple a change to botch. 😅

No problem, I will merge it and submit to Amazon, which might take a few days for approval

Thanks!
