Replace Categories Text on Detail Page

Hi,

I am using the following code to try to remove the categories (geodir_post_taxomomies) from the details page. I then want to replace it with my own function, so that the Category: label is not shown (only the category links themselves are).
I found an example of this here https://wpgeodirectory.com/support/topic/change-title-text-for-category-links-on-detail-page/#post-19133

Shouldn’t this code remove it?

remove_action( 'geodir_details_main_content' , 'geodir_action_details_taxonomies', 30 );

I also tried this from the post I linked to above, and it did not work either:

remove_action('geodir_details_main_content' , 'geodir_details_taxonomies', 10 );

Thanks.
