Panel Button in the system tab

Hey there,
I was curious about how I could show a custom panel button in the system tab only? For exemple for a way to redirect to the hosting solution or something like that ?

Following the exemple here, would something like that work out of the box?

'panel' => [
  'viewButtons' => [
    'system’ => [
      'analytics' => [
        'icon' => 'chart',
        'text' => 'Analytics',
        'link' => 'https://my-analytics.com/'
      ]
    ]
  ]
]

Thanks.
