How to specify datasource id to scheduler telerik ASP.NET Core

Question

I need client-side filtering with Scheduler. I wish to use Filter with Scheduler. For this, I need to specify datasource id to Scheduler. Different other components accept string parameter in Datasource, but Scheduler isn't. What to do?

View:

@(Html.Kendo().DataSource<CalendarDayVM>()
    .Name("daysSource")
    .Ajax(d => d.Read("Read", "WorkingCalendar"))
    )

@(Html.Kendo().Filter<CalendarDayVM>()
    .Name("filter")
    .MainLogic(FilterCompositionLogicalOperator.And)
    .Operators(c => c.String(s => s.Contains(KendoLocalizer["Contains"])))
    .Fields(c =>
        c.Add(e => e.ApplicantFullName).Label(UserLocalizer["FullName"]).EditorTemplate("UserEditor")
    )
    .DataSource("daysSource")
    )

@(Html.Kendo().Scheduler<CalendarDayVM>()
    .Name("working-calendar")
    .Date(DateTime.Now)
    .DataSource("daysSource")
    )
    .Views(views => { views.MonthView(); })
    )

Datasource call in Scheduler chain is marked red.
