Segment to get a single hit after an event occurs
I'm trying to define a segment to get me the single hit after a particular event happens. I've tried a number of combinations of sequential segments and exclusions but nothing seems to get just the one hit.
The question I'm trying to answer is:
What was the Page Type (v12 and p1) immediately after the customer interacted with the chatbot (event220)?
I've tried the following:

and also:

But these don't limit to just the one hit.
How do I get just the single hit? Can I use something like Entry page - does that still work after a sequential segment?
Thanks!
