Can't access Whatsapp voice notes

I am currently developing a task to transcribe voice notes from WhatsApp. My current focus is on evaluating the transcription quality by sharing files from the File Manager to an AutoShare command.

I have observed that sharing files from the "Download" folder functions correctly. However, when attempting to share files from the original WhatsApp directory (located at /Internal storage/Android/media/com.whatsapp/WhatsApp/Media/WhatsApp Voice Notes), the system indicates that the file cannot be found.

Any clues?
