If you accidentally lost or deleted a chat history with a user, don't worry! You can easily retrieve it. Simply go to the user's profile page and send them a new message. Once you do that, the chat will reappear in your conversations.
Alternatively, you can access your "Chats" page and find your "Hidden dialogs". From there, select the chat you want to unhide, click on the three dots, and choose "Unhide chat" from the options.
If you're still having trouble finding the chat after trying the above steps, feel free to reach out to our Customer Support Team. We'll gladly assist you by providing a direct link.
