In need of a secondary menu below the mainmenu

Hello!

I am using the themes function for page jumping which kind of limits me how I can add additional items to the menu.
I have other portions of my website that wont be apart of the inline single main page style. How I’d like to accomplish this is just add a second menu that gets displayed below the main. I’d like it to behave just like the main menu does (IE: looks, staying at the top when scrolling down, etc.).

I did look up how to do this and began to follow steps here + further research to try to see what I could make work. https://www.templatemonster.com/blog/add-navigation-menus-wordpress-theme/

Below are commented out attempts that I tried one at a time to see how I could get this to work.
Themes header.php

<?php elseif ( has_nav_menu( 'primary' ) ) : ?>
		<div id="site-navigation-wrapper">
			<nav id="site-navigation" class="main-navigation" role="navigation">
				<?php
					wp_nav_menu( array(
						'theme_location'  => 'primary',
						'menu_id'         => 'primary-menu',
						'fallback_cb'     => 'wp_page_menu',
						'items_wrap'      => '<ul id="%1$s" class="%2$s">%3$s</ul>',
						'walker'          => new Pique_Menu(),
					) );
				?>
			</nav><!-- #site-navigation -->
			<?php
			/*
			<nav id="site-navigation2" class="main-navigation" role="navigation">
				<?php 
				 		wp_nav_menu( array( 
							'theme_location' => 'Secondary',
							'menu_id'		 => 'Secondary',
							'fallback_cb'	 => 'wp_page_menu',
							'items_wrap'      => '<ul id="%1$s" class="%2$s">%3$s</ul>',
							'walker'          => new Pique_Menu(),
						) ); 
				 	?>
			</nav><!-- #site-navigation2 -->
			*/
			?>
		</div>
		<?php endif; ?>
		<?php
		/*
		<!-- Using the id/classes of the main menu for secondary menu -->
		<div id="site-navigation-wrapper-2">
			<nav id="site-navigation-2" class="main-navigation-2" role="navigation">
					<?php 
				 		wp_nav_menu( array( 
							'theme_location' => 'Secondary',
							'menu_id'		 => 'Secondary',
							'fallback_cb'	 => 'wp_page_menu',
							'items_wrap'      => '<ul id="%1$s" class="%2$s">%3$s</ul>',
							'walker'          => new Pique_Menu(),
						) ); 
				 	?>
			</nav><!-- #site-navigation -->
		</div>

	</header><!-- #masthead -->
