You can use Array.filter to filter out the items in the array which don't match the condition:

const desiredProp = "A"

const collection = [{
  inner_obj: {
    prop: "A"
  }
},
{
  inner_obj: {
    prop: "B"
  }
}]

const filtered = collection.filter(e => e.inner_obj.prop == desiredProp)

console.log(filtered)

You can try this

collection.find({"inner_obj.prop": "A"})
