Finding Redundant elements that are now surplus to requirements

I’m wonder if, after developing an app, is there a way of finding elements that don’t actually do anything because they were experimental or were replaced by fine tuning the app as it was developed? I have some elements in my app that I no longer need because while creating it I felt they could provide a helpful reference later on but I haven’t referred to them.
I know I’m probably supposed to have kept a record of these but I didn’t so, in the same way that there used to be ways of identifying “dead links” in old web design software, is there a way of finding elements that are now surplus to requirements?

Maybe next time you could put them in a popup….

Bubble has a reasonable search feature if you can think of some point of reference to search for
