How to get MeetingId or onlineMeeting by using meeting ThreadId

[Yang-Lu]

Hi Graph talents,

I meet an issue here. 

I only got the meeting ThreadId like this 

19::meeting_NTg0NmQ3NTctZDVkZC00YzRhLThmNmEtOGQ3M2E0ODdmZDZk@thread.v2

Is it possible to get the MeetingId or the onlineMeeting object of this meeting?
