Get the default JsonWriterSettings used by Spring for Mongodb

to map a mongodb document to a json. we can use the following method

val json = document.toJson()

but this method maps the document as it is without changing the type of ObjectId or anything else.

for example when the mongodb document is

{
     _id: ObjectId("xxx")
}

the output will be :

{"_id": {"$oid": "61d31135273a9076d6306993"}

to convert the document by changing the type ObjectId to String we can use JsonWriterSettings

val jsonWriterSettings : JsonWriterSettings = JsonWriterSettings.builder()
    .objectIdConverter { value, writer -> 
        writer.writeString(value.toHexString())
    }
    .outputMode(RELAXED)
    .build()

val json = document.toJson(jsonWriterSettings)

And the result will be :

{"_id": "61d31135273a9076d6306993"}

My question here, how to get instance of the default JsonWriterSettings used by Spring which parameterized by all other types like Date and my custom converters?
