Get teams link in Graph Api onlineMeeting

When I create online Meeting using either of the end points in graph API:
1. Calendar (create Event)
2. Cloud Communication ( create onlineMeeting)
while specifying onlineMeetingProvider as "teamsForBusiness", I get a Skype link in response although I have specified "teamsForBusiness".
Following are responses I got using these API endpoints narrating the issue.
