So I have a really simple ClearCollect statement:
ClearCollect(colTechTeam, Office365Users.DirectReportsV2("someone@somewhere.com"))
This works a treat. But, for the life of me, I cannot determine how to now query against the contents of the collection.
When I look at it in the Editor, I see this:

I expected to see the table of users right there. But they're buried under that value, here:

What you're seeing is the first X columns in the Claims record for each user returned. I didn't bother showing all and left out the actual data.
In that data of course, is a 'mail' column. I want to compare values in that column to the current user but can't figure out how.
I was trying to use the below to create a filtered collection which will have 1 or 0 records depending on result.
ClearCollect(
colFilteredTechTeam,
Filter(colTechTeam, mail = varCurrentUserEmail)
)
But mail is not a valid column name in the colTechTeam collection.
