Mongoose return id instead of _id in populate method

I have two related models: Recipe and User.

When I fetch a recipe and the related user from the database using populate(), I want the returned user object to have the id property instead of the _id property.

const recipe = await Recipe.findOne({ _id }).populate('user', '-password');

When I log the value of the user model, I want to get this:

{
  id: 5eea82b11a97e9429ca61778,
  name: 'John Doe',
  email: 'johndoe@gmail.com'
}

I tried adding the id property to the user object, it didn't change anything. I still got the _id property.

recipe.user = { ...recipe.user, id: recipe.user_id };

    noteSchema.set('toJSON', {
  transform: (document, returnedObject) => {
    returnedObject.id = returnedObject._id.toString()
    delete returnedObject._id
    delete returnedObject.__v
  }
})

This is what i use to remove the underscores - You can just transform the document and delete the bits you dont want
