State parameter with Client Credentials grant type flow

Hi All

Could you please let me know how to send state parameter with Client Credentials flow (Implement authorization by grant type | Okta Developer)?

We have a custom auth server setup in Okta that invokes an inline hook (token). Is there a way to send the state param with client credentials or any other param/header with this flow that gets carried over to inline hook event object?

Thanks

Shray
