How to populate the meta object in custom controller?

Hi, here is an example from Strapi blog post:

// ./src/api/order/controllers/order.js
    
    ...
    module.exports = createCoreController('api::order.order', ({strapi}) => ({
      confirmOrder: async (ctx, next) => {
        ctx.body = "ok"
      },
      find: async (ctx, next) => {
        // destructure to get `data` and `meta` which strapi returns by default
        const {data, meta} = await super.find(ctx)
        
        // perform any other custom action
        return {data, meta}
      }
    }));
