I'm used to doing X in Contrast, why is it greyed out or missing on CVE Shield Free?

CVE Shield Free tier is read-only outside of setup and monitoring, so several actions available elsewhere in Contrast aren't available here yet. You can view incidents, including details, evidence, and associated CVEs and observations, but you can't close, reopen, assign, or comment on them. IP management, SIEM integrations, and role-based access control aren't available either, there's no per-user permissioning on Free tier, and there's no SIEM endpoint to export to. None of this is hidden or broken, it's how Free tier is scoped at launch. Paid tiers add these capabilities as they become available.
