+Inherit verifyToken options from clerkClient.
+The below code now works as expected: (requires CLERK_SECRET_KEY env var to have been set)
+```ts
+import { clerkClient } from "@clerk/clerk-sdk-node";
+
+// Use the default settings from the already instanciated clerkClient
+clerkClient.verifyToken(token)
+// or provide overrides the options 
+clerkClient.verifyToken(token, {
+  secretKey: 'xxxx'
+})
+```
