How do I close an unselected TAB?

I'm trying to implement a closable TAB bar, but I'm having some problems with it. Go straight to the code

TabInfo tabInfo = new TabInfo(fn.apply(newTabIndex));
tabInfo.setText(path);
AnAction action = ActionManager.getInstance().getAction("MartinaRightSideTabToolbar");
DefaultActionGroup actionGroup = (DefaultActionGroup) action;
tabInfo.setTabLabelActions(actionGroup, TabInfo.ICON);

 the action set in tabInfo:

public class CloseTabAction extends DumbAwareAction {
   private Project project;

   public CloseTabAction() {
      getTemplatePresentation().setText("Close Tab");
      getTemplatePresentation().setIcon(AllIcons.Actions.Close);
      getTemplatePresentation().setHoveredIcon(AllIcons.Actions.CloseHovered);
   }


   @Override
   public void actionPerformed(@NotNull AnActionEvent e) {
      this.project = e.getProject(); //If TAB is not selected, this value is empty
      JBEditorTabs rightRequestTab = ViewHolder.getInstance(project).getRightRequestTab();
      rightRequestTab.removeTab(rightRequestTab.getSelectedInfo());
   }
}

I wonder if there is an easier way to close the TAB？
