Description Not Appearing in Calendar Events from Email Markup Schema Confirmation Emails

Question

We are currently facing an issue wherein the "Description" field is not displaying in Calendar events created through confirmation emails utilizing the Email Markup Schema.

Here is the current Email Markup Schema:

<script type="application/ld+json">
    {
    "@context": "http://schema.org",
    "@type": "EventReservation",
    "reservationNumber": "12d2ds2",
    "reservationId": "12d2ds2",
    "reservationStatus": "http://schema.org/ReservationConfirmed",
    "underName": {
        "@type": "Person",
        "name": "Lisa"
    },
    "provider": {
        "@type": "Person",
        "name": "Kira and Morrison"
    },
    "reservationFor": {
        "@type": "Event",
        "name": "The Adventures of Kira and Morrison",
        "startDate": "2023-11-21T19:00+05:30",
        "endDate": "2023-11-21T23:00+05:30",
        "eventAttendanceMode": "https://schema.org/OfflineEventAttendanceMode",
        "eventStatus": "https://schema.org/EventScheduled",
        "location": {
            "@type": "Place",
            "name": "Snickerpark Stadium",
            "address": {
                "@type": "PostalAddress",
                "streetAddress": "100 West Snickerpark Dr",
                "addressLocality": "Snickertown",
                "postalCode": "19019",
                "addressRegion": "PA",
                "addressCountry": "US"
            }
        },
        "description": "The Adventures of Kira and Morrison is coming to Snickertown in a can't miss performance.",
        "performer": {
            "@type": "PerformingGroup",
            "name": "Kira and Morrison"
        },
        "organizer": {
            "@type": "Organization",
            "name": "Kira and Morrison Music",
        }
    }
}
    </script>
