What’s the best way to register an anchor support field to an existing ACF field group, if possible? I don’t need a total custom block unless it’s the only way to add an Anchor field. I only need the anchor to create a sub-menu on the page linked below for easy navigation. This is where the CPT and ACF are set up where we need a submenu so users can easily navigate to each state: https://fintechmaindev.wpengine.com/alc-reg-testing
Using Elementor builder Loop Grid element.
I did find this post and saw Support Anchor True registers but again trying to avoid making a total custom field. https://support.advancedcustomfields.com/forums/topic/anchor-in-wp-blocks/
