[WPF] Cancel command bound to a button

[mujahidislam]

Hi All, Im struggling to implement logic for cancelling a reactive command generated by source generators. Basically I have following in my view model

[ReactiveCommand(CanExecute = nameof(CanLogin))] private async Task LoginAsync(CancellationToken cancellationToken)

And in my view I have bind this command to a button as below

this.BindCommand(ViewModel, vm => vm.LoginCommand, v => v.LoginButton) .DisposeWith(disposables);

However I cant find a way to cancel the cancellationToken on lets say when user click "Cancel" button. Would appreciate if team here can suggest an elegant way to do so, the one I can think of is creating another composite command but thats unnecessary additional command and will need to be done in every view model and every command I need it. I was hoping reactive command could expose an API for cancelling it.
