Hidden fields

Hi,

I have an endpoint that returns user information:

 const user = await req.payload.findByID({
            collection: 'user',
            id: user_id,
            showHiddenFields: true,
            depth: 0
        })

However, it keeps returning hidden fields.

The hidden fields in user collection :

 {
      type: 'group',
      name: 'verif',
      admin: { hidden: true, readOnly: true, },
      fields: [
        { type: 'checkbox', name: 'verified',  defaultValue: false, admin: { hidden: true } },
]
}

btw , i dont understand the difference between admin:{hidden:true} and just hidden:true

there is also all createdAt and stuff that i dont want to show in my result
