Get login ID in browser script

Hi All

Kindly, is there is any way I can get the user row ID who is currently login using browser script

for example this method TheApplication().GetProfileAttr('Login Name') will retrieve the login name but not the ID and when I am trying to query for the ID using the name the ExecuteQuery method cannot work on browser script

Siebel: 8.1.1.10

on Linux redhat

DB 11.2.0.4.0

Thanks ...
