title: Path for icon used in smart button
body: <p>I am not able to find path for icon used on smart buttons for e.g. In MRP we are having "Bill of Materials" button and icon name is "fa-flask".</p>
  
  <p>I already checked in web/staic/src/img/icons and local module too.</p>
  
  <p>Is it stored somewhere in binary form or is it some kind of fonts?</p>
