How to hide/disable the "More Options" link when displaying the vCalendar in Gmail

Question

Using Ical.Net library, a vcalendar similar below is generated:

    BEGIN:VCALENDAR
    METHOD:REQUEST
    PRODID:-//github.com/rianjs/ical.net//NONSGML ical.net 4.0//EN
    VERSION:2.0
    BEGIN:VEVENT
    ATTENDEE;[email protected];PARTSTAT=ACCEPTED;RS
    VP=TRUE:mailto:[email protected]
    DESCRIPTION:This is the description text
    DTSTAMP:20200604T075151Z
    DTSTART:20200604T165500Z
    LOCATION:
    ORGANIZER;CN=PHN:mailto:[email protected]
    SEQUENCE:0
    STATUS:CONFIRMED
    SUMMARY:Testing
    TRANSP:OPAQUE
    UID:LJf40Nfh2mZ+Ta1JFhlYRZDh2By3qeY6UMA6vcy525M=
    END:VEVENT
    END:VCALENDAR

In one email recipient, it shows up as: Add To Calendar image

However on another email recipient, it shows up as:
