How to refresh the .NET MAUI SfPullToRefresh from ViewModel

SfPullToRefresh is fully MVVM compatible and can be refreshed by binding a property in the view model to the SfPullToRefresh.IsRefreshing property.
SfPullToRefresh also provides support for SfPullToRefresh.RefreshCommand that will be executed when the pulling is completed and the pointer is released. You can also pass a desired object as parameter to the SfPullToRefresh.RefreshCommand using the SfPullToRefresh.RefreshCommandParameter.
The CanExecute() method of SfPullToRefresh.RefreshCommand will be fired when the pulling action is performed. Returning false in the command’s CanExecute() will cancel the pulling and the SfPullToRefresh.RefreshCommand will not be executed.
