Trying to call function by using db.eval("functionName()") in mongoDB compass version 4.4 But getting error as TypeError: db.eval is not a function

Question

db.system.js.insertOne({
  _id: 'getMachinewiseLogDat',
  value: function () {
    return db.Smx_22235_ShiftOEEDaily.aggregate([
      {
        $group: {
          _id: '$machineName',
          maxlogdate: { $max: '$logDate' },
        },
      },
    ]);
  },
});

db.eval('getMachinewiseLogDat()');
