Use this code to reproduce

let resources = [{ id: 'r1', name: 'Google', eventColor: 'blue' }];
let events = [{ id: 1, name: 'Meeting', startDate: '2022-02-11 14:00', endDate: '2022-02-11 17:00' }];
let assignments = [{ eventId: 1, resourceId: 'r1' }];

const calendar = new Calendar({
    // Start life looking at this date
    date : new Date(2020, 9, 12),

    resources: resources,
    events: events,
    assignments: assignments,

    sidebar : {

        resourceFilter : {
            multiSelect   : true,
            selectAllItem : true
        }
    },

    appendTo : 'container',

    features : {
        eventTooltip : {
            // Configuration options are passed on to the tooltip instance
            // We want the tooltip's left edge aligned to the right edge of the event if possible.
            align : 'l-r'
        }
    }
});
