UI Builder built record producer application. Where are the objects?

[Joseph2]

I have a question about the UI Builder Portal and the record producer application I built. I followed a course on your site to create this application. The record producer appears on a page seemingly out of nowhere. I want to add a button on the web page, not necessarily on the record producer itself, though either option would be fine.

I tried to find how to place a button on the record producer, but I can't locate the objects that make up the developed page around the encased record producer to enhance it. Where is the page setup that encases the record producer? Why is it so difficult to add a button in the UI Builder setup for the record producer?

Can  you share some screenshots about what it is you are trying to accomplish? 

Record producers normally are used on portals, not within workspaces (ui builder).

Its a UI builder generated page from the Portal App Shell.  I linked the catalog item to a RP in events.  It generated a page with the RP encased.
