I have two custom fields created for pages, not posts, in WordPress. How can I display the values of these custom fields in a block editor, such as Elementor, without the use of a plugin like ACF? I've read many articles with directions on placing custom code in either the functions.php, single.php, or page.php. However, there are no directions on how to call upon these custom fields within the content.

Here is what I would like to do:

• Add a custom field to a page using native WordPress custom fields
• Display this custom field anywhere I want to on a page using a shortcode
