Hi, i want to override the admin panel index page /admin/ the one that includes the documentation links to meet the business UI. Also, i need to customize the background color for the LoginPage - not the auth card - but all the surrounding area the default color is F6F6F6 and i want to change it to my primary color/ add some assets and all that stuff. But unfortunately can’t override it.
