Visually indicating user to change orientation of device

I am developing a site which has a component which is optimized for desktop or big view-ports, and tells users to use the "Tablet in landscape mode". When not on mobile, a message saying "Use tablet or phone" is shown. The text is fine but I am unable to put something that can visually tell a person to rotate the tablet.

What is the most efficient way to tell the user to use the tablet in landscape orientation?
