Hi when I want to use the check availability tool via google calendar - how do I set it up? According to the docs I just have to connect my google account and then it has access. But when i try to check availability during a test call it tells me that it gets an error. Additionally when i try to test the checking availability tool, it tells me that URL is not set, but i cant set it anyhere and response is just {}. Would be very grateful when somebody can help me out! :)
