Locally added fonts not loading in block editor

add_filter( 'generate_editor_styles', function( $editor_styles ) {
$editor_styles[] = 'wp-content/themes/generatepress/assets/css/admin/editor-style.css';

return $editor_styles;
} );

This is what I'm using and it's the only editor-style.css I can find. But, I'm still not getting the headlines to work.

Hi bjbowen,

Did you add the font following this instruction?
https://docs.generatepress.com/article/adding-local-fonts/

If so, could you open a new topic and link us to your site?

Please also attach the name of the local font.
