I see that there is an action around rendering fields: acf/render_field action. Is there an action around rendering the submit button? I’d like to add a custom cancel button next to the submit button.
Unfortunately, there isn’t any hooks that I’m aware of that will let you alter that part of the ACF form. You’d probably need to build custom JavaScript and insert it that way. https://www.advancedcustomfields.com/resources/adding-custom-javascript-fields/
