Basically, a Outlook event may contain a videocall URL in 2 different ways: 1) the event location may be a specific URL (such as `https://teams.microsoft.com/...`). In this case, we use it as `videocall_location` instead of classic `location`. We use a list of patterns to identify these specific URLs among classic locations. 2) the event may have an attribute `isOnlineMeeting` set to `True` and the attribute `onlineMeetingUrl` set with the URL. In this case, we use this `onlineMeetingUrl` as `videocall_location`. opw-2601669 closes odoo/odoo#74785 Signed-off-by: Arnaud Joset <arj@odoo.com>
