Export a selected group as .png in Photoshop (Script)

exportSelectedGroup.jsx

            // Restore the visibility of all layers
            setAllLayersVisibility(true);

Why is this still needed in newer PS Versions?

• "Quick Export" or "Export As.." trim the exceeding pixels from the group, this one does not
• it is a one step action and not a file menu
