 You can call `setCSPTrustedTypesPolicy(policy: TrustedTypePolicy | Promise<TrustedTypePolicy> | null)` from JavaScript to set a [CSP trusted types policy](https://web.dev/trusted-types/), which can perform (synchronous) filtering or rejection of the `fetch` response before it is inserted into the page:
 
 ```ts
-import { setCSPTrustedTypesPolicy } from "include-fragment-element";

 import DOMPurify from "dompurify"; // Using https://github.com/cure53/DOMPurify

 The policy has access to the `fetch` response object. Due to platform constraints, only synchronous information from the response (in addition to the HTML text body) can be used in the policy:
 
 ```ts
-import { setCSPTrustedTypesPolicy } from "include-fragment-element";
