I'm looking for the file in which I can find the full edition menu template

in header.php I have this code

<nav id="site-navigation" class="navigation main-navigation" role="navigation">
					<button class="menu-toggle"><?php _e( 'Menu', 'twentythirteen' ); ?></button>
					<a class="screen-reader-text skip-link" href="#content" title="<?php esc_attr_e( 'Skip to content', 'twentythirteen' ); ?>"><?php _e( 'Skip to content', 'twentythirteen' ); ?></a>
					<?php wp_nav_menu( array( 'theme_location' => 'primary', 'menu_class' => 'nav-menu', 'menu_id' => 'primary-menu' ) ); ?>
					<?php get_search_form(); ?>
				</nav><!-- #site-navigation -->

He wants to get to the menu list , so where can I find this code from files ?

<div id="navbar" class="navbar">
				<nav id="site-navigation" class="navigation main-navigation" role="navigation">
					<button class="menu-toggle">Menu</button>
					<a class="screen-reader-text skip-link" href="#content" title="Przeskocz do tre?ci">Przeskocz do tre?ci</a>
					<div id="primary-menu" class="nav-menu" style="
"><ul><li class="page_item page-item-2 current_page_item"><a href="https://tomeknobokto.nazwa.pl/test/">Sample Page</a></li><li class="page_item page-item-8"><a href="https://tomeknobokto.nazwa.pl/test/?page_id=8">Strona 1</a></li><li class="page_item page-item-10"><a href="https://tomeknobokto.nazwa.pl/test/?page_id=10">Strona 2</a></li><li class="page_item page-item-12"><a href="https://tomeknobokto.nazwa.pl/test/?page_id=12">Strona 3</a></li><li class="page_item page-item-14"><a href="https://tomeknobokto.nazwa.pl/test/?page_id=14">Strona 4</a></li><li class="page_item page-item-16"><a href="https://tomeknobokto.nazwa.pl/test/?page_id=16">Strona 5</a></li><li class="page_item page-item-18"><a href="https://tomeknobokto.nazwa.pl/test/?page_id=18">Strona 6</a></li><li class="page_item page-item-20"><a href="https://tomeknobokto.nazwa.pl/test/?page_id=20">Strona 7</a></li></ul></div>
					<form role="search" method="get" class="search-form" action="https://tomeknobokto.nazwa.pl/test/">
				<label>
					<span class="screen-reader-text">Szukaj:</span>
					<input type="search" class="search-field" placeholder="Szukaj …" value="" name="s">
				</label>
				<input type="submit" class="search-submit" value="Szukaj">
			</form>				</nav><!-- #site-navigation -->

			</div>

where can I find this code from files ?
