Send Audio via URL in Question Node for WhatsApp Channels

We’ve added support for sending audio files in the Question Node when the input is an audio URL.

If you share an audio URL in the question node, it will be sent as an audio file to the user.

This feature works with both the Official WhatsApp Channel and the Custom WhatsApp API Channel. Supported audio formats include .aac, .amr, .mp3, .m4a, and .ogg (with OPUS codecs only).

The maximum file size supported is 16 MB.
