Some of my Whatsapp group chats contain about 100mb of voice messages and I want to get rid of them. However, they are not being displayed as "media".
On Android I could just go to the Whatsapp data folder and delete them from there but I can't access that on iOS.
I've also found the whatsapp support being useless, so I am trying here.

Now, after 1000 views on this question it's worth updating my answer:
Recently, a function has been added to Whatsapp that lets you delete ALL voice messages from a chat.
(You can also delete other stuff in there but I wanna keep all of that haha)
