In which task and step of the codelab can this issue be found?
Step One
Describe the problem
println(displayAlertMessage(operatingSystem, emailId)) println(displayAlertMessage(operatingSystem, emailId))
Not so much as a bug as a suggestion:
"display" is a verb and in console programming means the same thing as print. As a programmer, my first thought on this was to remove the println and just call displayAlertMessage. In other languages and conventions, display isn't something that has a return value of other than success or failure.
println(generateAlertMessage(...)) would get the result that you are striving for, as it would prompt the user to use a return statement.
I may have missed, but I did not see in the unit that println() will print the return type of a function if it doesn't provide a return type. I think this could be confusing to newer programmers when they get output like:

There's been a new sign-in ... Kotlin.Unit
They may not know where Kotlin.Unit comes from.
