Approve pending Harness STO security exemptions (waivers) at their current scope or elevate them to Project, Org, or Account scope. Users say "approve" for both in-scope approval and higher-scope elevation — do not require the word "promote". Supports approving one exemption or a mixed list where each row has a different approval scope. Default workflow lists pending exemptions in chat (paginated preview) so the user picks by row number — no copying from the Harness UI. Use when a user wants to approve, sign off on, or clear pending exemptions, waive approvals, org-wide approval, or account-wide approval. Trigger phrases: approve exempt, approve exemption, approve waiver, sign off exemption, clear pending exemption, approve for org, approve for account, org-wide approval, account-wide approval, pending exemptions.
