Read a batch by IDs from Mongo in Kotlin

I have a document collection like:

{ "_id":"ABC", "job": {...} }

How to read a batch of Jobs given a collection of IDs from Mongo DB in Kotlin?

We search like this:

MongoClients.create(clientSettings).use { client ->
    val db = client.getDatabase(dbName)
    val coll = db.getCollection(collName)
    val filter = Filters.`in`("_id", jobs.ids)
    val res = coll.find(filter).map{ it.get("job") /* ??? */  }.asIterable()
    return JobBatch(res)
}

Please see /* ??? */ - How to convert Document to Job class?
