How to show acf field values in custom template

Hello, I am using a plugin to show my cars listings the plugin has a single listing page where it shows details of a single listing
in my custom fields group, I made some custom fields and set the location to
post type = listings
when I echo it it’s displaying the values on frontend and works well but the problem comes when
I created a separate template in wp and use a parameter in the URL
https://localhost/valueautos/beyond-value-listing/?listing_id=587

here and getting the current listing base on id in URL and when I echo custom field in this template its not showing any information
Kindly help and what to do in this situation.
