I'am wondering if someone has worked with review Workflows ?
I want to add a provisioning node (Service Now) when a review revoke an access of a user.
Are you referring to the workflows found under the Reviews menu? Those are meant to handle escalations (ie. A reviewer hasn't done the work assigned to them). You can create a request from this like revoke the access. For this reason, you wont see nodes like the provisioning command node there. The actual processing of the request however is done using the workflows configured under the Requests->Workflows menu. The overview page will help you configure what request workflow should be used from reviews. For what you are describing, I think you want to look at the fulfillment workflow associated with an application or directory. This workflow is ultimately called from the request workflow to do the actual work once any approvals that are configured are complete.
