Publish URL Pattern

I need to create a button (Not the HTML button, that is already created, I refer to connect an HTML button to a payment button inside Payzard plugin) that will serve in two different pages. On landing page one the button works as expected but I was not able to connect the same button on page two.

So, looking into “Advance Settings -> Publish Options” I found an option name “Publish on all matching pages” but requires a “Publish URL Pattern”.

How “Publish URL Pattern” works? Is this option allows me to use the same button on both pages? If not, how do I do the be able to use the same button on both pages without creating a new button inside Payzard plugin?

Thanks in advance!
