Modifying the login page via index.html

Is there a possibility to add a link to the index.html page that will only be displayed on the login home page, and when I log in, that link will not be displayed anymore?

It used to be possible in some older versions, but now I tried, but the link remains visible even when I log in.

You would have to add it in the code.

Yes, I added to the LoginPage.jsx file and now it is working fine.

Thank you.
