After initial setup for a new workflow of type Workflow with UI, you must set permissions for the workflow to let it be seen by appropriate logged-in users.
Restart the Gateway container.
Set access permissions for your workflow from the Workflow Permissions page in BlueCat Gateway. (See Configuring workflow permissions in the BlueCat user interface.)
After you set permissions, the new workflow will appear in the Available Actions menu for users who are members of the assigned groups, grouped by the Category that you specified for it.
You can now edit your new workflow's _page.py file with the code and functionality of your workflow.
