The LinkedIn Community integration is available, but it's not found under "actions -> import". Instead, it's accessible as an action for specific tasks. The integration is included in Pro+ plans and offers two main actions:
1. Enrich Social Metadata with LinkedIn Community
2. Find Post Audience with LinkedIn Community
Both actions require you to bring your own API key. If you're not seeing these options or need help setting them up, you might want to request human assistance for more specific guidance on your account.
