Hide Empty Field

Hello! I’ve only recently started using the awesome ACF plugin, and I’m using it to create Elementor templates.

I have used it here to create a button link “Read article” https://lboi.rapidwebsites.com.au/italy-comes-to-broke-2019/ – I’m trying to work out whether there’s a way to hide this button if that field is blank in the post?

I found this article https://www.advancedcustomfields.com/resources/hiding-empty-fields/ but when I added this using Code Snippet plugin I broke my website …

Any advice would be greatly appreciated 🙂

Regards
Melanie
