What this integration does
The primary way to use Calendly in VeloCMS is the Calendly scheduling block in the page builder: paste your public Calendly URL into the block's inspector and it renders a live booking widget on the published page — no OAuth connection needed. Optionally, connecting your Calendly account in Admin → Plugins → Calendly unlocks a convenience layer: an event-type picker in the admin panel, so you can select from your real Calendly event types instead of typing a URL by hand. The embed itself works identically whether or not you connect an account.
