There are 3 participants in the workflow. They can approve/reject the task of the current item. I want every participant to be able to approve/reject only their own tasks, not other participants.
For example: When Ece approve the task, the task assign to Joe. But Ece sees the task assigned to him and can approve/reject Joe's task. I don't want it. I want Ece not to be able to approve/reject other tasks. How can I make it happen? Thank you.
