X DevApi - C# strongly typed objects (no replies)

I'm using MySQL 8.0.28 enabled X DevApi plugin listening on port 33060. I'm looking for Api reference examples that demonstrate on how to store strongly typed objects as a document in a given schema.

Ex.

public class Payload
{
[BsonId]
[BsonRepresentation(BsonType.ObjectId)]
public string id { get; set; }
public int JobId { get; set; }
public Dictionary<string, Core> Data { get; set; }
}

public class Core
{

public string[] Meta { get; set; }
}


#### Insert into Doc Store

public async Task InsertDocumentAsync(Payload entity)
{
if (entity is null)
{
throw new ArgumentNullException(nameof(entity));
}

try
{

var result = await _dbCollection.Add(entity).ExecuteAsync();
entity.id = result.GeneratedIds[0];
}
catch (Exception ex)
{
_logger.LogError("Error inserting into mysql doc store", ex);
}
}


It inserts a document successfully with following values -

column - doc value - '{\"_id\": \"00006356dc0a0000000000001908\"}'
column - _id value - BLOB
column - _json_schema value - '{\"type\": \"object\"}'


I could fetched the document but unable to cast result to class type "Payload"

#### fetch doc from store

var d = dbCollection.GetOne(guid);
var doc = Utf8Json.JsonSerializer.Deserialize<Payload>(d.ToString());


Is there any other methods to do above operations? I've been dealing with pretty complex type structure which has multiple complex properties under root type.
