draft: test insights 4.0 feature

Created by: Joelkw

We should test the 4.0 feature along the following scenarios:

https://docs.google.com/spreadsheets/d/11aQqWEVe_S11Ff_W9ntjjLwaV9XsfkmhuJGZ2z8wqAQ/edit#gid=0

For each scenario, we should:

1. link to the search used in the box
2. color the box red or yellow if it didn't work as a user would expect / as it is scoped to
3. test every available aggregation (toggle through all options)
4. test saving it as an insight for every available aggregation
