+/// Triggers Credential Share mode on a nearby eligible Apple Border Router (tvOS(27.0)).
+///
+/// This method scans for Thread credential sharing capable Apple Border Routers, selects an eligible device, and requests to generate an ephemeral 9-digit code and start credential sharing mode.
+///
+/// When you call this method, an alert appears asking for user permission to
+/// access credentials.
+///
+/// - Parameters:
+///   - completion: The completion handler the framework calls when the
+///     one-time admin code becomes available.
+///
+/// > Concurrency Note: You can call this method from synchronous code using a completion handler,
+/// > as shown on this page, or you can call it as an asynchronous method that has the
+/// > following declarations:
+/// >
+/// > ```swift
+/// > // Completion handler form:
+/// > func enableCredentialSharingMode(completionHandler: @escaping (String?, Error?) -> Void)
+/// >
+/// > // Async form:
+/// > func enableCredentialSharingMode() async throws -> String
+/// > ```
