+ * import { DefaultAzureCredential, getBearerTokenProvider } from "@azure/identity";
+ * import { createPipelineRequest } from "@azure/core-rest-pipeline";
+ *
+ * const credential = new DefaultAzureCredential();

+ * const getAccessToken = getBearerTokenProvider(credential, scope);
+ * const token = await getAccessToken();
+ *
+ * // usage
+ * const request = createPipelineRequest({ url: "https://example.com" });
+ * request.headers.set("Authorization", `Bearer ${token}`);
+ * ```
+ *
+ * @param credential - The credential used to authenticate the request.
+ * @param scopes - The scopes required for the bearer token.
+ * @param options - Options to configure the token provider.
+ * @returns a callback that provides a bearer token.
