Set Different Work Hours for Each Day in Blazor Scheduler

In Blazor, you can set the required work hours in Scheduler, which visually highlights the cells within the specified work-hour range. In the following code example, you can set different work hours for Scheduler cells based on the day of the week by using the SetWorkHoursAsync method. Before setting custom work hours, reset the default work hours by using the ResetWorkHoursAsync method.
