For me link like this works: https://calendar.yahoo.com/?v=60&title=Event&st=20230418T190000Z&et=20230418T194400Z

It converts time zone to user's time zone. But you need to check you have set correct time zone in https://calendar.yahoo.com/setting
Yahoo (and Outlook) uses not time zone from browser, but time zone from user's settings
