cannot bind data to class and retrieve it from anther form

Question

I have been stuck at this bump for 3 days now, here is the issue:

I have a class named Models, I need to bind specific information to it, when the user logs in it retrieves all the information and then uses it across the application which I haven't been successful in accomplishing, or if there is a way to directly retrieve embeded documents value from mongodb for example:

    {
      "_id": {
        "$oid": "61f05d962e19875728f53884"
      },
      "username": "YRbicLcyVwY=",
      "email": "mR+0ULwyFaY=",
      "pin": "sonPU0DOWEA=",
      "age": "/4A+0B/jLko=",
      "creation date": "zbS8yBCepb4rTRsPSuN+1K9VryjXyZYR",
      "admin": "BjBSqbmjcwg=",
      "password": "dqAWwktjoFc=",
      "theme": "po8uCcnsvoo=",
      "timer": "dRvJzHdD/vQ=",
      "Questions": {
        "Question 1": {
          "Question": "Q",
          "Answer 1": "Q",
          "Answer 2": "Q",
          "Answer 3": "Q",
          "Answer 4": "Q",
          "Correct Answer": "Q"
        },
        "Question 2": {
          "Question": "Q",
          "Answer 1": "Q",
          "Answer 2": "Q",
          "Answer 3": "Q",
          "Answer 4": "Q",
          "Correct Answer": "Q"
        }
    }
}

I wanna access Question 1 Question & Answers so I can use it in the application, so upon logging in this is what happenes

public Models Modd;
Modd = BsonSerializer.Deserialize<Models>(result);
