Imagine the following schema:

const GroupSchema = new Schema(

  {
    name: { type: String },
    
    description: { type: String },
    
    admin: { type: String },
    
    members: [{ user: { type: Schema.Types.ObjectId, ref: "User" } }],
  }
  
);

I'm trying to select and populate 10 items of the members array without returning other fields like this:

  [
      { 
        user: {
          name: "Alice",
          username: "alice"
        }
      },
      
      { 
        user: {
          name: "Bob",
          username: "bob"
        }
      },
      
       { 
        user: {
          name: "Jack",
          username: "jack"
        }
      },
      
       { 
        user: {
          name: "Alex",
          username: "alex"
        }
      },
    ]

I've already tried:

communityModel
      .find()
      .slice("members", 10)
      .populate("members.user", "name username");

but it returns other fields of the group model like admin and description. I also tried .select('members') but this one returns the entire array of members.
