Created a ABAP Workflow which have three levels of Approvals. Now My Requirement is that if the First level had approved the Workitem and putting Decision Note and workitem will go to Second level and Second level person  should be able to see  in My Inbox Fiori App that what firstlevel  had put in the Decision Note and in the same way third level person should be able to see the First level Decision Note and Second Level Decision Note in My-Inbox Fiori App. Right now it is not appearing and any configurations are there which we can achieve.
