As the comment above, add the fild ID in your model with

[BsonId]
[BsonRepresentation(BsonType.ObjectId)]
public string id { get; set; }

using:

using MongoDB.Bson;
using MongoDB.Bson.Serialization.Attributes;

and then when you insert the object, mongo return the ID of the document into the fild ID of the model.
