Adding coauthors to HotWP theme

Hello, i’d like to add coauthors tags to HotWP theme. I haven’t found the tags in functions.php but i found them in postmeta.php
The code is below but i haven’t figured out how to add it in there. Could anyone please help me? Thanks!

This is the original code:

if ( ! function_exists( 'hotwp_post_tags' ) ) :

/**

 * Prints HTML with meta information for the tags.

 */

function hotwp_post_tags() {

    if ( 'post' == get_post_type() ) {

        /* translators: used between list items, there is a space after the comma */

        $tags_list = get_the_tag_list( '', esc_html_x( ', ', 'list item separator', 'hotwp' ) );

        if ( $tags_list ) {

            /* translators: 1: list of tags. */

            printf( '<span class="hotwp-tags-links"><i class="fa fa-tags" aria-hidden="true"></i> ' . esc_html__( 'Tagged %1$s', 'hotwp' ) . '</span>', $tags_list ); // WPCS: XSS OK.

        }

    }

}

endif;

if ( ! function_exists( 'hotwp_style_9_cats' ) ) :

function hotwp_style_9_cats() {

    if ( 'post' == get_post_type() ) {

        /* translators: used between list items, there is a space */

        $categories_list = get_the_category_list( esc_html__( '&nbsp;', 'hotwp' ) );

        if ( $categories_list ) {

            /* translators: 1: list of categories. */

            printf( '<div class="hotwp-fp09-post-categories">' . __( '<span class="screen-reader-text">Posted in </span>%1$s', 'hotwp' ) . '</div>', $categories_list ); // WPCS: XSS OK.

        }

    }

}

endif;

if ( ! function_exists( 'hotwp_style_9_postmeta' ) ) :

function hotwp_style_9_postmeta() { ?>
