Use the TaskURL for a clickable link (Alert Composer)

Summary:

I am trying to use the${TaskURL} as the URL of a clickable link (a hyperlink) in Alert Composer for Alert "Task Assigned for Performer".
For the below alert, I want "Execute Task" to link to ${TaskURL} , as showing ${TaskURL} directly means showing the long and "ugly" URL to the HCM instance.

I tried pasting ${TaskURL} in the "link" pop-up that is available in the editor, that does not work. Adding it in "source code editing" mode removes the token for the <a href=" "> element upon Applying the change. Is there no way to use the token as a hyperlink?
