I really don’t know much about elementor.
I cannot find a “Post” widget, but I can find a “Posts” widget.
I do see a Query section, but cannot find a way to add a PHP code snippet to this?
The only way I can describe it is the code I have provided. Beyond this it is a question about Elementor, not a question about ACF.
I will try to help you (becuase I am in the process of learning elementor) but you’re going to need to tell me exact steps get to and do what you attempting to do starting from the WP Dashboard.
