What you need to know is how templates work in WordPress. Templates are ‘instructions’ on how to ‘build’ page output. They are contained in your theme’s file structure. (Which is why your question is better asked on the theme’s support page, instead of here.)
The actual template file (a PHP file) which is used based on the template hierarchy, explained here: https://developer.wordpress.org/themes/basics/template-hierarchy/ . The entire ‘theme developers handbook’ is useful if you want to understand how pages are built in WP.
I can’t give you an exact answer, as it depends on your theme. And theme questions are not the purpose of this place; the support pages of your theme are the place for that.
But in general, the above link will help you start your understanding of how templates are used to ‘build’ pages.
