How to hide call recordings?

Hi Gerardo,
 
In regards to your concern, unfortunately right now there's no plan of adding this feature and it's currently not on the roadmap to add this.
 
Any agent with permission to access tickets can access call recordings. You can only permit end-users from accessing live recordings in their requested tickets. 
 
I've also checked available apps in the marketplace, however, seems that there's none available at the moment.
 
I've taken a look and found that other users are discussing similar needs here:

You can up-vote that original post and add your detailed use-case to the conversation. Threads with a high level of engagement ultimately get flagged for product managers to review when they go through roadmap planning.
 
Specific examples, details about impact, and how you currently handle things are the most helpful things to share to help our product teams understand the full scope of the need when working on solutions.
 
We truly value customer feedback and your voice and votes in the product feedback topics in the community help influence future Zendesk functionality.
 
Thank you and have a wonderful day ahead!
