JQuery toggle a OL list with headings

Question

I have an OL list that works as an accordion with jQuery toggle, and I also have a sidebar with anchor links linking to the OL list headings. I would like to make so that the anchor links link to and toggle open the respective headings.

Can someone help me add to this script so that when I click on the anchor link, the respective section div opens?

Thanks!!

jQuery('#sections > li > div').hide();

jQuery('#sections > li > h2').click(function(e){
    
    e.preventDefault();
    // hide all div
    var $li = jQuery(this).parent();
    var $div = jQuery(this).parent().find('div');
    jQuery("#sections > li > div").not($div).hide();
    jQuery("#sections > li").not($li).removeClass('active');
    
    // here is what I want to do
    $div.toggle();
    $li.toggleClass('active');
    
});

You can use the href of the anchors to trigger the clicks manually.

$('#sections_list li').click(function(e) {
  e.preventDefault();
  var href = $(this).find('a').attr('href');
  $(href).click();
})

jQuery('#sections > li > div').hide();

jQuery('#sections > li > h2').click(function(e) {

  e.preventDefault();
  // hide all div
  var $li = jQuery(this).parent();
  var $div = jQuery(this).parent().find('div');
  jQuery("#sections > li > div").not($div).hide();
  jQuery("#sections > li").not($li).removeClass('active');

  // here is what I want to do
  $div.toggle();
  $li.toggleClass('active');

});

$('#sections_list li').click(function(e) {
  e.preventDefault();
  var href = $(this).find('a').attr('href');
  $(href).click();
})
