The answer was there I just had to keep on looking. Here are the connector settings that worked for me.

{
    "name": "MongoAccountSinkConnector",
    "config": {
        "connector.class": "com.mongodb.kafka.connect.MongoSinkConnector",
        "name": "MongoAccountSinkConnector",
        "topics": "ACCOUNT",
        "connection.uri": "mongodb://...",
        "database": "local",
        "collection": "Account",
        "key.converter": "org.apache.kafka.connect.storage.StringConverter",
        "key.converter.schemas.enable": "false",
        "value.converter": "io.confluent.connect.avro.AvroConverter",
        "value.converter.schemas.enable": "true",
        "value.converter.schema.registry.url": "http://...:28081",
        "mongodb.delete.on.null.values": "true",
        "delete.on.null.values": "true",
        "document.id.strategy.overwrite.existing": "true",
        "document.id.strategy":"com.mongodb.kafka.connect.sink.processor.id.strategy.ProvidedInKeyStrategy",
        "transforms":"hk",
        "transforms.hk.type":"org.apache.kafka.connect.transforms.HoistField$Key",
        "transforms.hk.field":"_id",
        "writemodel.strategy": "com.mongodb.kafka.connect.sink.writemodel.strategy.ReplaceOneDefaultStrategy"
    }
}
