How to properly define GoLang struct for nested arrays [closed]

Question

Here is how my mongoDb document looks like:

{
  "_id": 111,
  "updateDate": "2000-10-01T04:00:00Z",
  "updateLogs": [
    [
      {
        "updatedBy": "user1",
        "updatedDate": "2020-06-23T21:23:37.138Z",
        "info": "test"
      },
      {
        "updatedBy": "user1",
        "updatedDate": "2020-06-23T21:23:37.138Z",
        "info": "test2"
      }
    ],
    [
      {
        "updatedBy": "user2",
        "updatedDate": "2020-06-23T21:23:37.138Z",
        "info": "test"
      },
      {
        "updatedBy": "user2",
        "updatedDate": "2020-06-23T21:23:37.138Z",
        "info": "test2"
      }
    ]
  ]
}

and this is how I try to define struct to use for such document:

type DocumentsData struct {
    Id         int32        `bson:"_id" json:"_id"`
    UpdateDate time.Time    `bson:"updateDate" json:"updateDate"`
    UpdateLogs [][]LogValue `bson:"updateLogs,omitempty" json:"updateLogs,omitempty"`
}

type LogValue struct {
    UpdatedBy   string    `bson:"updatedBy" json:"updatedBy"`
    UpdatedDate time.Time `bson:"updatedDate" json:"updatedDate"`
    Info        string    `bson:"info" json:"info"`
}

and here is how I retrieve the documents:

var myDocuments []DocumentsData
cur, err := docCollection.Find(context.TODO(), bson.D{}, &options.FindOptions{})


for cur.Next(ctx) {
    var myDoc DocumentsData
    cur.Decode(&myDoc)

    myDocuments = append(myDocuments, myDoc)
}

but for some reason it doesn't build nested arrays in response. Please advise whether my struct definition is correct for such document structure
