Newbie question : display owner information on password login page

I want to display the owner’s information of a share including name, image and shared path on the password login page of the share (should password protected).

I think add an app is better. But as I’m not familiar with app development, is directly change the core application would be easier ? Any suggestion is welcome. Thanks in advance.


would this be a feature that you contribute back to Nextcloud or a custom modification for your needs?

After study the source, I think it is out of my current ability.

I’ll found a freelancer to to finish this and contribute back the code.
