Share Availability: Share Availability Based on Multiple Calendars (e.g. Teammate + Self)

Allow users to view and select time slots based on the availability of both themselves and a teammate (or multiple teammates) within the app. The goal is to easily share these combined available time slots via email without needing to manually check each person's calendar and type out the times. The feature doesn't need to be a booking link—just an efficient way to view combined availability and share it, similar to what tools like Notion Calendar offer.
