Passing parameters to universal login template page

I use the universal login (the new experience).
I need the template to dynamically choose between two backgrounds, but I did not find a way of how to do that.
I there a way to make this work?
I use the SPA auth0 package.

thanks for the help!

Hey there!

Basically New Universal Login compared to Classic one is not intended for heavy customisation so I would expect such functionality from the Classic one if at all. Are you willing to switch to classic one, if so I can research that and check if such option exist.
