Blog element show full content.

on one installation i got for a page “aktuelles” – ID: 2061
i want to show the whole content for the blog entries with taxonomy “aktuelles”

on newer enfold versions this does not work anymore.

function custom_avf_blog_content_in_loop( $blog_content, $current_post, $blog_style, $blog_global_style ){
  global $avia_config;
    $pages = [ 2061 ];
    if( ! in_array( $avia_config['real_ID'], $pages ) ){
      return $blog_content;
    }
  return 'content';
}
add_filter( 'avf_blog_content_in_loop', 'custom_avf_blog_content_in_loop', 10, 4 );

How can the entire content be displayed?
