To enable the Approval Workflow feature, you must:
Click on the OKRs drop-down menu > Manage sessions
Click the Create a session button
Follow through the steps and create a session
Navigate to the Workflow section
Choose how many people you want to approve every OKR in this session
Click Use workflow
Click Create session

Pro-tip:
Only account administrators and custom-made roles can create a new session or edit an existing one. Thus, they're the only ones who can enable the Approval Workflow feature.

Pro-tip:
If account administrators enable the feature, they can't go back and disable it. That's why, we've added a confirmation state to inform the session creator that there is no going back to "Don't use" after the session is created with a Workflow enabled.
