Mongo $lookup nested array 3 levels deep using mongoose

I have this inside services model:

services: [
      {
        category: {
          ref: 'ServiceCategories',
          type: Schema.Types.ObjectId
        },
        types: [
          {
            ref: 'ServiceType',
            type: Schema.Types.ObjectId
          }
        ]
      }
    ]

I have this inside incidents model:

  outsideServices: {
      ref: 'OutsideService',
      type: Schema.Types.ObjectId
    }

so when requesting incidents from api the response would be like:

[
  {
    category: '5cf655135a1b72106777c238',
    types: ['5cf655a85a1b72106777c239']
  },
  {
    category: '5cf656525a1b72106777c23b',
    types: ['5cf656835a1b72106777c23c']
  }
];

How it's possible to lookup both categories and types ref and keep the structure above in my response?

Here's what I've tried so far but I can't get the desired results:

aggregate.lookup({
      from: 'outsideservices',
      let: { serviceId: '$outsideServices' },
      pipeline: [
        { $match: { $expr: { $eq: ['$_id', '$$serviceId'] } } },
        {
          $lookup: {
            from: 'servicecategories',
            let: { services: '$services.category' },
            pipeline: [{ $match: { $expr: { $in: ['$_id', '$$services'] } } }],
            as: 'category'
          }
        },
        {
          $lookup: {
            from: 'servicetypes',
            let: { services: '$services.types' },
            pipeline: [
              { $match: { $expr: { $in: ['$_id', '$$services'] } } }
            ],
            as: 'types'
          }
        }
      ],
      as: 'outsideService'
    });

The wanted result/outcome is like the response above but with populated documents and not ObjectIds
