How do script comments and approval work?

Open a shared (Team library) script in the editor; the collaboration block shows its status: Draft → In review → Approved.

• Owners and editors click "Submit for review" (the team owner gets an email), "Approve" (the requester gets an email), or "Reset".
• Anyone on the team can add a comment ("Add a comment…" → "Comment"), tick teammates under "Notify:" to email them, and "Resolve" / "Reopen" a thread. You can delete your own comments.

Personal (non-shared) scripts don't have comments.
