How do you want to do this?

Everyone adds their own sideYou get a link and a PIN to send the others. Each person adds their chats and voice notes from their own phone. Nobody sees anyone else's side. This is the fairest way. I'll add all the evidence myselfYou upload the chats, screenshots and voice notes once, for everyone. No links to send, and the fastest way to a verdict. It will say only you added to it.
