Discount Page App Name Missing

How can I show my app’s name on a discount’s page like the below app did? When I create a discount with my app, it just says ‘App’.


I’m thinking this can be achieved with Admin UI Extensions:

It only adds a button inside the ‘More actions’ menu. Does it have any additional capabilities beyond that?

This tutorial mentions a target for admin.discount-details.function-settings.render - could you try that target?
