Blazor EventCallback with Multiple Params - how to respond to event in parent host control

I have a blazor component with an EventCallBack parameter that utilized the new struct format allowing multiple arguments

[Parameter] public EventCallback<(EmployeeShiftDay, DateTime, DateTime)> NewDayScrolledIntoView { get; set; }

eventcallback is invoked in child normally as such

await NewDayScrolledIntoView.InvokeAsync(p1, p2, p3);

In my host page I have the corresponding method to handle the invoke

private void NewDayInView(EmployeeShiftDay dayInView, DateTime weekStart, DateTime weekEnd){   ...}

How do I add the markup for this EventCallBack in the host component - I need of course 3 params not just one

<ShiftCardScroller NewDayScrolledIntoView="@((args) => NewDayInView(args))" ></ShiftCardScroller>
