Can we get the depth of the evaluation as well along with output documents?

db.employees.aggregate( [ { $graphLookup: { from: "employees", startWith: "$reportsTo", connectFromField: "reportsTo", connectToField: "name", as: "reportingHierarchy" } } ] )

"reportingHierarchy" => should provide output like {depth: 1, documents: [{}, {}]}

It will help us to reduce no. of queries in order to find depth of children.
