display acf field as label in cf7 form

Hi,
this is probably just too simple to find a solution via google or plugin support –
I want to create a customized form which is displayed in different posts and shows certain information from the post as headline or text information in the form and the generated e-mail without necessarily being linked to a certain form field.
I tried to solve this using Advanced Custom Fields, but I do not find a way to simply display the content of a field in my form. Shortcode like this does not work:
[acf field=’titel’]
Using Dynamic Text Extension Plugin, adding the content of fields as default text in form fields works fine, but what I really want to do is much simpler and I just can’t find a solution.
Thank You
Mike
