How to make the progressbar change examples when it reaches 100%?

Question

Unity

I am making a simple developmental game, and I need to make sure that when the progress bar reaches 100%, the examples change and the number changes, such as 1/10, 2/10.

Answer 1

The progressbar here is generally a display element, it should not manage anything other than itself.
Examples should be changed by the component where you change these same values.
