How to show full screen activity indicator on tvos?

How to show activity indicator like here?

In this moment i'm using custom UIViewController that have activity indicator. I just show it with

show(_ vc: UIViewController, sender: Any?)

but i feel like it's wrong way. The reason is that in that case i have problem with menu button. I want to catch press action and pass in to paren view controller. Now press button just close view controller with activity indicator.

In the app provides by apple i saw loader screen like on the screenshot and it work the same way i want. I didn't found something like this in the UIKit so i have no idea what to do.
