    Add an custom class to comment_author_link using filters. When using get_comment_author_link this function to fetch comment author link.

    Just add this code into functions.php

    // filter for get_comment_author_link
    function wpdocs_custom_get_comment_author_link( $content ) {
    	$extra_classes = 'text-decoration-none text-primary fw-bold mb-0';
    	return preg_replace( '/url/', 'url ' . $extra_classes, $content );
    add_filter( 'get_comment_author_link', 'wpdocs_custom_get_comment_author_link', 99 );
