My friend and I chatted some personal information between us in a group chat being absent minded. So now we are stuck. We need to delete those messages permanently. So is it possible to delete the messages permanently so that no other group member can see the chats? None of us are admin of the group. So if we request the admin, can he do that (he is a trustworthy person) ? Does he have this authority?
I am sorry to say so, but it is absolutely not possible to do that at all.
When you delete the conversation from your account, it will just go out of your view for ever, but will be available to be read by everyone else.
