Is there a way to get media file extension without downloading?

[nova flare]

From what I searched on discord and what I read on the docs, I will need to download the media instead of being able to filter them by their name/extension.

For whatsapp processed media (media not sent as files/attachments/documents) there is no filename per say, but you can use message.deprecatedMms3Url to obtain the info

For actual media files you can use message.filename to get the file name without downloading

do note, downloadMedia doesnt save to disk, it just creates a buffer, so if your worry is diskspace, you dont need to worry about it
