You would have to put these queues and schedule in separate folders. You could then define separate accesses for separate users. You cannot choose specific graphs or queues without separating them in this way.
It looks like you have an older version of Orchestrator. Click on the icon to the upper right. You’ll find Users there and the roles can be set under that menu.
Do we have any other way to give access to specific users, without separate folder ?
i mean with default folder, i have to give access for a user to specific process and queue etc.
