How to re-hide fields after Reset A Form action

Checkbox LICENSES has a Mouse Up action to hide/show textbox Text4 with the following script:

if (event.target.value === "Off") {
this.getField("Text4").display = display.hidden;
} else {
this.getField("Text4").display = display.visible;
}

Button Clear Form has a Mouse Up action to reset a form.

I checked the checkbox LICENSES, textbox Text4 appears so I can enter some information.

When I clicked on the Clear Form button, the checkmark was cleared from checkbox LICENSES and the information I entered was cleared from textbox Text4. However the textbox Text4 itself stays visible.

How to re-hide all fields that were originally hidden after I Reset A Form?

Thank you.
