Adding a URL on Mac OSX Login Screen

We are trying to customize the Login Screen for Mac machine to have a button to opens a secure browser with a pre-defined URL. The below is the sample login screen:

We used below links:

Customize Login Screen Mac OSX (SFAuthorizationPluginView)

Custom login/lock screen in OS X Mavericks

https://developer.apple.com/documentation/securityinterface/sfauthorizationpluginview

However, We could not add a button or a link on the custom login to screen.

If there is a good tutorial or article for this?
