I've tried a solution.

Create a rectangular shape around the word or text (written in black) you want change the opacity after a click.

Fill this shape in white color with 100% transparency and no line.

Create a new state for this shape (i.e. called 50%) where the transparency is set to 50 %. Add a trigger on the shape to change state to 50% when clicked.

The text seems to be written in light grey after the click.

Is it clear for you ?
