Most Important note: the app needs to be installed on both your smartphone and on the Fire TV (Stick). In the settings developer the ADB debugging must be enabled.
The "buttons" are not left or right clicks, but for swipes in the appropriate direction (work only moderately well) at the bottom of the touch pad, you just have to click briefly tap the touchpad.
If the touchpad also allows the holding and dragging, I give 5 stars, until then it will remain at 4
