in Chrome there seems to be a popup window asking for notification permissions. This can currently not be cirumvented using a workflow. Switching to a different browser solves the issue for now.
had another look at the workflow, obviously there was also an outdated locator specified. Please re-download the example workflow, then it should work. Before running, please also make sure to update to the latest Selenium Nodes release, which fixes above mentioned issue with notification permission.
