Context Sensitive user assistance plugin component not getting loaded on Fiori Launchpad

Hello Experts,

We are using a hub gateway system running SAP Fiori for SAP S/4HANA 1610 FPS02. We have followed the blog S/4HANA – HowTo: Activate context-sensitive help from SAP for configuring context sensitive user assistance. We have adjusted the web dispatcher profile parameters for User Assistance Content Platform and for script server. We have then setup the in-app help plugin on the launchpad designer by creating a catalog with a target mapping with the below properties and added the catalog to a PFCG role on the front-end server and assigned it to the users.

Semantic Object: Shell

Action: plugin

Application Type: SAPUI5 Fiori App

Title: Help

URL: /resources/sap/dfa/help/utils/adapters/fiori/

ID: sap.dfa.help.utils.adapters.fiori

Parameters:

product => SAP_S4HANA_ON-PREMISE

version => 1610 002

editor => false

With these settings when we access the launchpad via the web dispatcher the help icon is not visible in the launchpad header and we see the below error message pertaining to the help plugin component.

Can someone let me know where could we have gone wrong and how can we correct this error message so that the help icon shows up in the launchpad?
