Google web stories

I recently started with Google web stories. Have a few doubts:

1) How much time does it take to appear in results after publishing the story?

2) Do stories get indexed just like normal blog posts?

3) Do stories with multiple slides like 7-8 performs better than 2-3 slide stories?

4) I have installed story plugin in my wp, but how to know if I am getting views or not?

5) Any other thing I am missing here?

.

did you end up testing it yourself or not?
