How to use mongodb collation

I would like to query using monbodb collation, but I am not sure which parameters I should set.

I tried to see if it would work by setting collation on the same level as allowDIskUse: true, but the collation setting was not reflected.

  "collection": "Test",
  "aggregate": [ some aggregates ...] ,
  "collation": {
    "language": "ja",
    "strength": 1

mongodb version: 5.0.13
redash version: 8.0.2+b37747

Best regards
