Angular Scheduler Event Link Delete ContentMenu

Hi There,
https://code.daypilot.org/86334/angular-scheduler-event-links

On Gantt Chart, i was able to use contextMenuLink to right click on link to delete.

However on Scheduler Chart, cannot use contextMenuLink , compiler show 'contextMenuLink' does not exist in type 'SchedulerConfig'

config: DayPilot.SchedulerConfig ={
contextMenuLink: new DayPilot.Menu({
      items: [
        {
          text: 'Delete Link',
          onClick(args) {
            const dp = args.source.calendar;
            dp.links.remove(args.source);
          }
        }
      ]
    })
}

error:

 Object literal may only specify known properties, and 'contextMenuLink' does not exist in type 'SchedulerConfig'.

How to delete the event link on scheduler event?

Thank you
