KDE Connect has a feature that allows you to use your phone as if it was a touchpad to control the mouse on your computer. We want to add two nice buttons in the Action Bar (the top bar in many Android apps, that includes the title, the back button and some action buttons) to perform a right click and a middle click. The icons you need to design should represent the actions of clicking with each button. The icons have to be white-over-transparent, and you should provide scaled versions for the following resolutions: 96x96, 64x64, 48x48 and 32x32.
