# if you have dynamic keys that you need to match on
# use $objectToArray to be able to work with them easier
{ 
  $addFields: {
    keyValuePairs: { $objectToArray: "$myObjectWithDynamicKeys" },
  }
},{
  # now you can use filter and search it like any other array now that you know the keys
  $addFields: {
    myMatchedObject: {
      $filter: {
        input: "$keyValuePairs",
        as: "keyValue",
        cond: { $eq: ["$$keyValue.k", "$myPropertyOrValue"] },
      }
    }
  }
