Hey Kshitij,
the link is for the Weblient, not the portal. Novacura also offers a Portal, which is a bit different from the webclient and offers different Portlets to configure. Depending on the setup, the license and the installation you might not have Portal installed. if you have it you need to check with whoever setup the environment on what the address for the portal is. It should be something like: https://inzuscene-portal.test.novacuracloud.net or https://inzuscene-portal2.client.test.novacuracloud.net
Regards,
Johannes
