    try {
        // Get encrypted message from req.body
        const { message: cipher, iv } = req.body;

        // Decrypt it by using commt and parse it to object
        const result = JSON.parse(commt.decrypt({ cipher, iv }));

        // Get required parameters from decrypted result
        const {roomId, message} = result;


        // Save message to your database
        await MessageModel.create({
            roomId,
            type: message.type,
            senderId: message.senderId,
            createdAt: message.createdAt,
