What to change in the below script to add "State" condition

Hi,

In workitems, the below script makes a field mandatory if priority=medium. What changes needs to be done to add a condition that, the field should become mandatory only if "state=Assigned" and "priority=medium":

dojo.provide("org.example.workitems.providers.Priority");
dojo.require("com.ibm.team.workitem.api.common.WorkItemAttributes");

(function() {
  var WorkItemAttributes = com.ibm.team.workitem.api.common.WorkItemAttributes;

  dojo.declare("org.example.workitems.providers.Priority", null, {
    matches: function(workItem, configuration) {
      var sev =  workItem.getValue(WorkItemAttributes.PRIORITY);
      return (sev === "priority.literal.l3"); // Medium
    }
  });
})();
