How to add announcements in webcenter spaces page style so all pages created using this style will have the same announcements

Go to Administration –> Resources in web center spaces
Click on  Page Styles
Select a page Style you want to add a common announcement task flow. click edit and Edit Source



in the page add the below code in the place you want it .
<cust:panelCustomizable id="pc231">
                          <af:region value="#{bindings.announcementminiview1.regionModel}" id="r1"/></cust:panelCustomizable>


In the page Definition tab , Under the executables add the task flow tab as mentioned below. You can also pass the parameters for the task flow as required
<executables>
   <page viewId="#{WCAppContext.application.siteTemplatesManager.currentSiteTemplateViewId}" id="shellTemplateBinding" Refresh="ifNeeded"/>
      <taskFlow id="announcementminiview1" taskFlowId="/oracle/webcenter/collab/announcement/view/taskflows/mini-view-definition.xml#announcement-mini-view" activation="deferred" xmlns="http://xmlns.oracle.com/adf/controller/binding">
