Execute work Item approval thru SAP WebGui

We are currently sending approvals to the users rthough emails on Microsoft inbox to approve a PR.

The approvers are getting link to 'execute work item'(as shown below)

http://<SERVER>:8001/sap/public/bc/workflow/shortcut?sysid=QA2&logonid=&client=300&uname=BOYGLO1&langu=EN&transaction=*SWNWIEX&param=p_action%3DEXECUTE%3B%20p_wi_id%3D000000225003%3B%20p_appl%3DNOTIF%3B%20DYNP_OKCODE%3DONLI

which calls the standard SAPGUI installation(shortcut.sap)

I am wanting to use the SAPGUI web for users to approve the PRs.

I have ready have access and have configured SSO for webgui . Users are able to log in to webgui without any issues with SSO.

I tried modifying the public/bc/workflow/shortcut

SICF node to SSL and to use HTTPS  with no avail. (keeps calling SAPGUI).

any ideas on how I will be able to get the 'shortcut' to call the WEBGUI instead of creating an instance of SAPGUI?

thanks
