Code Help – Byline Authors Displayed

I cannot figure out which part of the code I should be editing to get multiple authors to show up in the byline. I have read the page on Publish Press and on WordPress, but still can’t figure it out.

I can’t even find a place where author or byline meta data has been coded.

Here’s the function code:

<?php
/**
 * Theme functions and definitions
 *
 * @package News-way
 */
if ( ! function_exists( 'newsway_enqueue_styles' ) ) :
	/**
	 * @since 0.1
	 */
	function newsway_enqueue_styles() {
		wp_enqueue_style( 'newsup-style-parent', get_template_directory_uri() . '/style.css' );
		wp_enqueue_style( 'newsway-style', get_stylesheet_directory_uri() . '/style.css', array( 'newsup-style-parent' ), '1.0' );
		wp_enqueue_style('bootstrap', get_template_directory_uri() . '/css/bootstrap.css');
		wp_dequeue_style( 'newsup-default',get_template_directory_uri() .'/css/colors/default.css');
		wp_enqueue_style( 'newsway-default-css', get_stylesheet_directory_uri()."/css/colors/default.css" );
		if(is_rtl()){
		wp_enqueue_style( 'newsup_style_rtl', trailingslashit( get_template_directory_uri() ) . 'style-rtl.css' );
	    }
		
	}

endif;
add_action( 'wp_enqueue_scripts', 'newsway_enqueue_styles', 9999 );

add_action( 'customize_register', 'newsway_customizer_rid_values', 1000 );
function newsway_customizer_rid_values($wp_customize) {

  $wp_customize->remove_control('main_banner_section_background_image');

I have tried just pasting the code suggested on the Publish Press page about this in a bunch of places, but none of that has worked.
