gio:permission-acquire (permission &optional cancellable)

permission -- a g:permission instance
cancellable -- a GCanellable instance, or nil

True if the permission was successfully acquired.

Attempts to acquire the permission represented by permission. The precise method by which this happens depends on the permission and the underlying authentication mechanism. A simple example is that a dialog may appear asking the user to enter their password.

You should check with the g:permission-can-acquire function before calling this function. If the permission is acquired then true is returned. Otherwise, false is returned.

This call is blocking, likely for a very long time, in the case that user interaction is required.
