      from: "leaders",
      let: { leader_id: "$leader_id" },
      as: "leaders",
      pipeline: [
        {
          $match: {
            $and: [
              { $expr: { $eq: ["$_id", "$$leader_id"] } },
              { organization: "Software Development" }
            ]
          }
        }
