Use checkPermissions with nested field

[Skaptox]

Steps to reproduce

Hello. I'm starting to use feathers. I don't know how to use checkPermissions with nested permissions without add permissions field to root of my model.

Expected behavior

{
            "_id": "5cb3bb8115afab14a74e5ad3",
            "email": "[e-mail]",
            "roleId": "5cb3af204ddf5e03c15868a9",
            "_include": [
                "roles"
            ],
            "roles": {
                "_id": "5cb3af204ddf5e03c15868a9"
                "permissions": [
                    "documents-types:*",
                ],
                "name": "documents-types admin",
            }
}

User hook

after: {
    all: [ 
      populate({ schema: userRoleSchema })
      ...
    ]

Documents-types hooks

before: {
    all: [checkPermissions({
      roles: [ 'documents-types' ],
      field: 'roles.permissions',
    })],
   ...
}

Actual behavior

It doesn't work. I had to add this hook to user to extract the permissions.

    after: {
    ...
    get: [(context) => { context.result.permissions = context.result.roles.permissions; return context;}],

System configuration

feathers --version 3.9.0
"feathers-hooks-common": "^4.20.7",
"feathers-mongoose": "^7.3.2",
