Ask HN: Apps for surveying availability for best time to have a board videocall?

[liface]

Use case: 6-7 people across three North American timezones. Need to meet once or twice a month for a board meeting over Google Meet. No one is on the same Google Calendar organization.

All I want is a link to a calendar so people block off times they aren't available. Then it produces a report of the times the most people are available, and I pick one.

Doodle is way too involved, as it goes in the reverse direction: I have to set up a bunch of stuff in advance: meeting name, duration, suggested times, etc.
