When you use the pen to tap the screen on the desktop or Photoshop, the right button function will be automatically triggered as the below screenshot shows. 

Please adjust it by following steps:

1. Open "Tablet setting";
2. Click the below button and select "Nib Click Sensitivity";

3. Adjust the value in the square box section into 0-15 (That is when the number on the right of Parameter Setting changed into 0-15)
