            } catch(deniedAlways: DeniedAlwaysException) {
                // Permission is always denied.
            } catch(denied: DeniedException) {

            }
        }

}

Android:

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
        
    val viewModel = getViewModel {
        // Pass the platform implementation of the permission controller to a common code.
        ViewModel(PermissionsController())
    }
    
    // Binds the permissions controller to the activity lifecycle.
    viewModel.permissionsController.bind(lifecycle, supportFragmentManager)
}

// Just pass the platform implementation of the permission controller to a common code.
let viewModel = ViewModel(permissionsController: PermissionsController())
