CSP issue when adding JavaScript code snippet to Shopify store

[DavidFG_OSP]

Hi There! 
I'm attempting to add a JavaScript code snippet to my Shopify store, but I'm encountering a Content Security Policy (CSP) error: "Refused to frame https://AAAAA.de because an ancestor violates the following Content Security Policy directive: 'frame-ancestors 'none'."

However, I need to include this iFrame snippet for a specific functionality on my store. What steps can I take to allow this JavaScript code snippet to execute without violating the Content Security Policy? Are there any safe and recommended ways to modify the CSP settings for my Shopify store to accommodate this?
