How to set up admin settings in plugin

Thanks. I have permissions for my plugin showing up, by setting its type as illustrated.

I’m still getting a 401 error when visiting the settings page of my plugin

    routes: [
      //  SETTINGS
      {
        method: 'GET',
        path: '/settings',
        handler: 'settings.get',
        config: {
          policies: [],
        },
      },
      {
        method: 'POST',
        path: '/settings',
        handler: 'settings.update',
        config: {
          policies: [],
        },
      }
    ],
  }```
