Feature Request: OSD Warnings/Messages in Telemetry Pages with Audio

Currently it is not possible to receive the warning messages (warnings, arming status flags, sanity checks, etc) in DJI FPV System custom OSD.

An alternative for users with DJI FPV System or without OSD would be to receive these messages on the telemetry page (If possible with a voice message related to the message).

Today I'm using DJI FPV System with GPS Rescue but it is very difficult to know for example why my quad is not arming (SANITY CHECKS). It is very difficult to know if GPS Rescue is available during the flight because we did not receive the message GPS RESCUE N / A for example.

It would be great to hear a voice saying "GPS Rescue Not Available" and "GPS Rescue Restored" when you have your goggles on your face.

Thank you!

Start by locating the telemetry-page implementation and any existing warning, arming-status, sanity-check, GPS Rescue, or audio-message handling in the Lua scripts. Check what DJI FPV telemetry data and OpenTX audio capabilities are available, then define how the requested warnings appear on the page and which messages can be spoken.
