Currently for any custom domain we get the same landing page.

Current State (links.utkarshchourasia.in) :

Expected State (link.utkarshchourasia.in) :

Something like this, which has a predefined template and the options to add shortened links from the dashboard could be a great idea.

So for links where Link Cloaking is enabled , the visitor can go to the root link(example.xyz/), they can view more available links instead of a blank landing page.
