add image to winops.widget

[knm100]

menu("winops") {
  item("focus", Focus );
  item("close", Close );
  item("(un)minimize", Function "ToggleMinimize" );
  item("(un)maximize", Function "ToggleMaximize" );
}

If I want to add image to the code shown above, is this possible? Is there a similar widget for reference?

menu("winops") {
  item(" focus%gtk-find", Focus );
  item(" close%window-close-symbolic", Close );
  item(" (un)minimize%window-minimize-symbolic", Function "ToggleMinimize" );
  item(" (un)maximize%window-maximize-symbolic", Function "ToggleMaximize" );
}

This is using stock icons but you can use /path/to/icon.[png|svg].
