How to remove my matching multiple object fields

[SwapnilSoni1999]

I have following data

"tracking": [
        {
          "pincode": "380061",
          "age_group": 18
        },
        {
          "pincode": "380061",
          "age_group": 45
        }
      ]
    }

I want to delete by matching pincode 380061 and age_group 45 and keep the one with age_group 18

I've tried

db.get('tracking').remove({ pincode: 380061, age_group: 45 }).write()

but it is not working

matching just by one obj props, maybe?

db.get('tracking').remove({ age_group: 45 }).write()

Thanks but I've solved issue by giving each entry a nanoid
