Any event participant can invite friends:

1. Go to the event page where you want to invite friends.
2. Click the “Participants” tab above the timeline.
3. In the “Participants” block, open the “Invitations” tab.
4. Click the “Invite” button next to your friend’s name.
5. Your friend will receive the invitation, and their name will appear in the “Invited” tab.

⚠️ Note: The invitation does not require a user to join — the final decision is always theirs. Private event content is visible to invited users.
