I did explained procedure for Cura and created a post processing script.  
Still “Thumbnail not found” appears and printer waits. In case I turn the button counterclockwise, a rectangle jumps from right to left, and printer starts to proceed printing when I press the button.

What is written in rectangles in right/left sides, I don’t know, probably “cancel/confirm” or “abort/contuniue”.
