Your preferred meeting duration can be set in your Dashboard here. You can choose a different duration for virtual and in-person meetings.
Clara will always follow your default meeting duration, unless you or a participant specifies otherwise. If you'd like a call to have a different duration, you can instruct Clara to do so when requesting the meeting. For example:
“CCing Clara to get a 15-minute call on the calendar”
"Looping in Clara to schedule a call for us. Clara, we will need 45 minutes."
