In spa page, how to include a widget

When creating a spa page, if your page needs a spa widget that does not auto load another page, you do not need to include the spa widget. You can simply create a <div> with the id,Instead of

 <div class="row mt-2">
 <div class="col-12 col-sm-12 col-md-12 col-lg-9 col-xl-10 p-3">
 {_{
 // Set widget uuid
 wuuid = "9cfaef69-2aa3-4b75-a4a0-4c4de2a3ebfb";
 // Build widget object
 wuuid = {
 "uid_position": wuuid,  "uid_widget": wuuid,  "uid_instance": wuuid
 };
  wconfig = {
 "rows" : {
 "ws_url": "",
 "selector_id": "ps_patient_edit_insurance_policy",
 "with_web_socket": "no"
 }
 };
 %include "/toolbox/module/sed/app_single_page/widget/w_manager.sn";
 }}
 </div>
 </div>

You can do

 <div class="row mt-2">
 <div class="col-12 col-sm-12 col-md-12 col-lg-9 col-xl-10 p-3">
 <div id="ps_patient_edit_insurance_policy"></div>
 </div>
 </div>

Since all js needed for the spa widget were already loaded in the first page (extranet) no need to reload it's code over and over.
