Microsoft graph API access problem when create online meeting or online meeting event

Question

I am trying to use "https://graph.microsoft.com/v1.0/me/events" or "https://graph.microsoft.com/v1.0/me/onlineMeetings" to create online meeting programmatically.

I used help from many resources specially this https://vikrantsdynamicsblogs.wordpress.com/2020/03/28/programmatically-create-the-teams-meeting/.

I have used this API to get token using password grant type "https://login.microsoftonline.com/{tenantId}/oauth2/v2.0/token" but the problem happened when I am calling "https://graph.microsoft.com/v1.0/me/onlineMeetings" I got 403 Forbidden

and when I am trying to call "https://graph.microsoft.com/v1.0/me/events" using the same access token I am getting this response

I have added delegate permission from Azure portal

Any Ideas why both are not working with me?

Authorization errors can occur as a result of several different issues, most of which generate a 403 error (with a few exceptions). We could refer to this doc to resolve Microsoft Graph authorization errors.

We cannot create online meeting via personal Microsoft account, if you are using work or school account, we need to ensure the account has the permission: OnlineMeetings.ReadWrite, if you are create online meeting via Application, we need OnlineMeetings.Read.All and OnlineMeetings.ReadWrite.All* permission, check this Create onlineMeeting and Online meetings permissions for more details.
