Ideally, the map should check TFGenerationSettings.usesTwilightChunkGenerator(ServerLevel). If the condition fails then display title text over the hotbar "The map seems unresponsive..."

I've got a better idea:
Maps can only be 'activated' in TF, maintain the display render from the TF so people can use it as decoration in other dims on item frames

Ah, I never specified “working” to “activating” but yes that’d be ideal
