You're in the way, but there's some work to so :)
Also, please fix static checks using prek (instructions are available in the docs)

1. In a second thought, I now wonder whether we should introduce the unwrap_single parameter at all, as it already returns the expected result (list[str]). It could be a nice feature for the while, at least until we align the rest of the operators.
   I'll be happy for more opinions, for now I keep it as is.

2. Following a recent incident, I'd rather merge this PR after ensuring that the system tests pass.
   @Abhishekmishra2808 if you're able to do so, I'll be happy if you could attach a screenshot that it runs succesfully for the modified operator. Otherwise, we'll wait for Google team or anyone else to run them.

@yuseok89 could you please test it also ?

I haven't used Google Ads before, so I couldn't go into as much detail as with other operator tests.
That said, I did manage to get GoogleAdsToGcsOperator working, so I'm sharing screenshots.

Test Screenshots

unwrap_single=False

unwrap_single=True

Thanks for running!
It looks like the effect is reversed though (when unwrap_single is False it's unwrapped).
Did you misplace the titles by chance? :)

Oh, you're right. That was my mistake 😅
Looking at the screenshot, the task names and behavior do match, and I've confirmed in my code that the task names and unwrap_single param are aligned.
I mixed up the screenshots when I moved them over.
I'll update that comment.
Good catch!
