This API is only available in the window context and not exposed to workers.
Instance propertiesUserActivation.hasBeenActive Read only
Indicates whether the current window has sticky user activation.
UserActivation.isActive Read only
Indicates whether the current window has transient user activation.
An object of this type is accessed via the navigator.userActivation property, and can be used to query information about a window's user activation state.
A user activation either implies that the user is currently interacting with the page, or has completed an interaction since page load. User activation can be triggered by a button click, pointer touch, or some other user interaction with the page.
There are two kinds of window user activation states:
See Features gated by user activation for more information and a list of APIs that require either sticky or transient user activation.

}
