You have the option to delete any chat, and/ or hide chats for any group you belong to if you no longer want to see them. In addition to sending text, chats let you share: Photos Videos Dual-Camera MeWe’s Emojis Stickers Doodles Files GIFs Voice messages and Private Posts. This is similar to a normal post that you share to your timeline, however, it’s only shared privately with whomever you’re chatting with.
