How to increment the value of an object in an array of objects. Mongoose and MongoDB

Question

I'm trying to create something like an award system and I'm looking for the best option to do that. Depending on which award was incremented I have to increase by one the value of it. This is what my model looks like:

 const CardSchema = new mongoose.Schema({
  awards: {
    "awardOne": 0,
    "awardTwo": 0,
    "awardThree": 0,
    "awardFour": 0
  },
  userId: {
    type: mongoose.Schema.ObjectId,
    ref: 'User',
    required: true
  },
})

Now what is the best way of incrementing by one for example awardOne.

exports.awardCard = asyncHandler(async (req, res, next) => {
  const id = req.params.id;
  const awardOption = req.body.award; //Name of the award
  const card = Card.findById(id)

   if(!card){
        res.status(200).json({
        success: false,
        message: "Card not found"
   }

  card.update ... //This is where I don't know how to manage the update

  card.save()

  res.status(200).json({
    success: true,
    card
  })
});

exports.awardCard = asyncHandler(async (req, res, next) => {
  const id = req.params.id;
  const awardOption = req.body.award; //Name of the award
  const card = await Card.findOneAndUpdate({"_id":id}, { $inc: { [`awards.${awardOption}`]: 1 } }, {new: true});

   if(!card){
        res.status(200).json({
        success: false,
        message: "Card not found"
   }

  res.status(200).json({
    success: true,
    card
  })
});
