Clockwise
Clockwise is a smart calendar assistant that frees up your time so you can focus on what matters.
Please be very careful when using Clockwise's Focus Time functionality, especially when you use booking links for people to schedule a time to chat with you. Focus Time can inadvertently leave few to no time openings for a conversation.
When you want to use Clockwise's Focus Time, I suggest limiting it to 6-8 hours a week to provide a chance for people to make time with you.

It’s suspected that setting Availability during Focus Time events as Free should allow booking link timings to work as expected. Thank you @Hussain Abbas.
