Book a chosen slot with `PATCH /rest/ats/applications/{application_id}/application-activities/{application_activity_id}/scheduled-interviews`. **Token scopes**: `ats:read`, `worker:read` **Beta**: this version requires the `X-Beta: true` request header and its contract may change before it is promoted to stable. It is scheduled to become stable on 2027-01-29.
