Use if-else node to select string to display while button is pressed (else display empty string).

I meant that the if-else should select what text to display. Using print-at, you might need to explicitly print spaces to clear what was previously printed:

puls… is a pulse-on-change node so the display gets updated whenever the text to display is changed.
