Prepend Archive Titles with Markup

Hi Tom,

Am using this code

add_filter( 'single_cat_title', 'generate_custom_archive_title' );
function generate_custom_archive_title( $text ) {
  if ( !is_admin() && is_archive() )
    return $text . 'Archive';
    
  return $text;
}

To add text to append text to archive title . It works but returns markup like this <header class"page-header"> <h1 class="page-title"> Uncategorized Archive</h1> </header>

The desired output is for the text to be prepended and wrapped in it’s own h tag not appended at the end.

Example <header class="page-header"> <h2 class="prepend-page-title">Archive</h2><h1 class="page-title"> Uncategorized</h1> </header>

I have tried using the ‘generate_archive_title’ to insert the prepend text but it’s gets outside the <header> tag.

Kindly assist.

Thank you
