Extended Notifications - Work Item UWL link not working

Hi all,

I need to have a link pointing to the Work Item in the Portal (UWL). Not to be opened in SAP GUI in Windows neither in HTML version for SAP GUI. I want the link in the email to open the work item as it was open from the UWL. I have tried several approaches but with no success. I am able to open it trough SAP GUI HTML (SHOW_ACTION_EXECUTE_AS = LINK1) and through SAP GUI for Windows (SHOW_ACTION_EXECUTE_AS = LINK2), but this is not what is expected. I have tried the following configurations:

But with no success. has anybody faced this issue or know how to solve it? It is a bit urgent.

Thanks in advance.
