Hi!
How can I hide empty answer hint button in course quiz question: https://drive.google.com/file/d/1hSHTKbiTVR8Q4BZ-n3Pm4VwTCV2DQRBG/view?usp=sharing
And in question pasted to post by shortcode: https://drive.google.com/file/d/13r5f5iJODGcIG6RAgjvlexC8nzYDBgf1/view?usp=sharing
But if there is answer hint, the button should be shown.
