Use this template and it is copied into your workspace as a workflow you own: every step is editable on the canvas, it can be renamed, pinned or archived (archiving pauses it), and it stays switched off until you turn it on. Test run walks the reads and conditions and reports what would be staged without staging it, and Run now works while the workflow is still switched off.
It runs on the schedule shown above. The templates ship in India time (Asia/Kolkata); change the day, hour and timezone on the trigger step.
Each post it drafts lands in Publish as pending approval; nothing is published until a person approves it there. Notifications go by email, and to any Slack, Discord or Microsoft Teams channel verified under Settings > Notifications.
