Get specific record at top after finding that specific user's data

    user_data = collection.aggregate([{
        '$match': {
            "user_id": user_id
        }
    }, {
        '$sort': {
            'created_at': pymongo.DESCENDING
        }
    }, {
        '$lookup': {
            'from': 'artwork_images',
            'localField': '_id',
            'foreignField': 'artwork_id',
            'as': "artwork_images"
        }
    }, {
        '$lookup': {
            'from': 'artwork_moods',
            'localField': '_id',
            'foreignField': 'artwork_id',
            'as': "moods"
        }
    }, {
        '$lookup': {
            'from': 'artwork_mediums',
            'localField': '_id',
            'foreignField': 'artwork_id',
            'as': "mediums"
        }
    }, {
        '$lookup': {
            'from':
            'artwork_collaborators',
            'localField':
            '_id',
            'foreignField':
            'artwork_id',
            'pipeline': [{
                '$lookup': {
                    'from': "users",
                    'localField': "user_id",
                    'foreignField': "_id",
                    'as': "collaborator_info"
                }
            }],
            'as':
            "artwork_collaborator",
        },
    }, {
        '$facet': {
            'data': [{
                '$skip': skip
            }, {
                '$limit': page_size
            }],
            'metadata': [{
                '$count': 'total',
            }],
        }
    }])

I am using pymongo to query, and i need to update above query so that, if i pass collection_id in match, then results will show that collection_id at top from that users artwork collection and then the rest of the collection with pagination
