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”.

再現手順にリンクされている Microsoft Graph application-post-onlinemeetings のドキュメントから始め、次に Python requests.post() のペイロードと、allowNewTimeProposals、isOnlineMeeting、onlineMeetingProvider の値を調べます。記載されている Teams アカウント設定でリクエストを再現し、レスポンスによってオンライン会議が作成されるのか、個人の予定が作成されるのかを判断します。原因が確認され、問題に対する修正が文書化されるか、想定される動作であることが示されれば完了です。
