Thanks for merging PR #35143 — great to see the .ics export officially back.
One thing I wanted to check: is there any possibility (or future plan) to authenticate this feed with a user token or API key, similar to how Discourse handles private RSS/Atom feeds (/topics/feed.rss?token=…)?
Right now /discourse-post-event/events.ics seems to work only for public events, which means Outlook / Google Calendar can’t subscribe to private categories.
Even a lightweight token-based approach (per-user or per-site, read-only) would make it possible to securely expose private events in calendar clients without having to proxy the feed through an external script.
Is that something that could be added, or is it already possible through an existing parameter I might have missed?
