when created Teams schedule with Graph api as a "Online meeting", but it was created "personal schedule"

Describe the bug

I would like to create a teams schedule with Micorosoft Graph api as a "Online Meeting", but now it was created as the "personal schedule".

Microsoft Graph api code is created in Python. Teams schedule info write in json file and call function "requests.post()". To make it an Online meeting, the following code is settings were made. payload 'allowNewTimeProposals' is 'true' payload 'isOnlineMeeting' is 'true' payload 'onlineMeetingProvider' is 'teamsForBusiness'

But it was created as the "personal schedule". I would like to know why I cannot register my schedule in “Online Meeting”.
