Does $setIsSubset (from MongoDB) work in Metabase?

1

I created a querry in MongoDB using aggregation framework and within that i used $setIsSubset which is only available from MongoDB 3.2

Unfortunately it ignores that line in the projection.

“Employee”: { “$setIsSubset”: [ “$helpParam”, “$role” ] }
Where helpParam is an array with only one element [“employee”] and role is an array with several roles.

We’re running Metabase 3.2 and i’m using Chrome as a browser.
Does Metabase support that function already?

Thank you a lot for your help!
