Working with Wake up page. Messaging the driver

Our platform has a functionality of sending messages to the driver. The message comes in a form of a push notification to the mobile app, if:
- driver is logged in to the mobile app
- we have the device token of driver's mobile device (normally is given upon successful authorization)
- the mobile app is open (active or minimized) on driver's mobile device

On this page you may:
- search for a driver you want to message or see the messages history
- see the messages that were sent to the driver
- enter the message text and send it to driver
- choose a template text for the message
- choose a notification sound that will be used for push notification (will work only if driver chooses a default notification sound in his device settings)
