Showing Co-Authors on post page

Question

I am trying to make my theme compatible with Co-Authors Plus plugin and show the co-authors of a post if had any.
I spent about 30 minutes trying to convince myself that I understood the following code to display post author and date:

function posted_on() {
    global $post;
    $author_id=$post->post_author;
    $time_string = '<time class="entry-date published updated" datetime="%1$s">%2$s</time>';
    if ( get_the_time( 'U' ) !== get_the_modified_time( 'U' ) ) {
        $time_string = '<time class="entry-date published" datetime="%1$s">%2$s</time><time class="updated" datetime="%3$s">%4$s</time>';
    }

    $time_string = sprintf( $time_string,
        esc_attr( get_the_date( 'c' ) ),
        esc_html( get_the_date() ),
        esc_attr( get_the_modified_date( 'c' ) ),
        esc_html( get_the_modified_date() )
    );


    $posted_on = sprintf(
        __( '<i class="entry-date">'. get_the_date( 'F d, Y' ) .'</i>' ),
        '<a href="' . esc_url( get_permalink() ) . '" rel="bookmark">' . $time_string . '</a>'
    );

    $byline = sprintf (
        __( 'by %s' ),


        '<span class="author vcard"><a class="url fn n" href="' . esc_url( 

            get_author_posts_url( $author_id )

        ) . '">' . esc_html( get_the_author_meta( 'display_name', $author_id ) ) . '</a>' . '</span>'

    );



    echo '<span class="posted-on">' . $posted_on . '</span><i><span class="byline"> ' . $byline . '</span></i>'; // WPCS: XSS OK.
} 

So I added a function:


        $byline = sprintf (
        __( 'by %s' ),

        /*Added this*/ if ( function_exists( 'coauthors_posts_links' ) ) {
    coauthors_posts_links();
} else {        

        '<span class="author vcard"><a class="url fn n" href="' . esc_url( 

            get_author_posts_url( $author_id )

        ) . '">' . esc_html( get_the_author_meta( 'display_name', $author_id ) ) . '</a>' . '</span>'
        }

    );



    echo '<span class="posted-on">' . $posted_on . '</span><i><span class="byline"> ' . $byline . '</span></i>'; // WPCS: XSS OK.
}

The function was supposed to work like…

IF THIS POST POST CONTAINS CO-AUTHORS,

DISPLAY AUTHORS AND CO-AUTHORS.

IF POST DOESN’T CONTAIN CO-AUTHORS,

SHOW THE DEFAULT AUTHOR LINK.

But that just made error. Could use a little advice.
