Message Media

The player adds no fields of its own to a Message media. Every field filled in the media is copied, as is and without validation, to dsplay_media, so the fields depend on the template:

• Countdown and Count Up
• Wi-Fi
• Meeting Room
• Flight Information
• Building Directions

Templates that need no media data (clocks, calendar, alerts, hotel rates, tide sheet, voice AI, etc.) only get the general fields.
