Issue updating online meeting after upgrade to 6.6.0

[ccea-dev-team]

I create an event with the online meeting flag set to true. Then I use the join url from this event to update it's backing online meeting to set a meeting co-organizer (this 2 step process seems to be the only way to set a co-organizer for an online meeting created from an event). This process worked fine in version 6.4.0 but after upgrading to 6.6.0 I get the following error when calling patch on the online meeting -

com.microsoft.graph.models.odataerrors.ODataError: Updating meeting type is not supported.

Code that worked in version 6.4.0 below. Error happening in 6.6.0 when the patch is called on online meeting at the end-

Some background to setting a meeting co-organizer for an online meeting created from an Event -

#1834

The way that was suggested there by @Ndiritu was to create the online meeting first, set the co-organizer, then use the join url when creating the Event. This didn't work as when the event is saved it overwrites the join url from the online meeting with its own join url. So I had to create the Event first then get the backing online meeting from that event and update the co-organizer on that. This worked fine on version 6.4.0 but now does not work on 6.6.0 with the error -

com.microsoft.graph.models.odataerrors.ODataError: Updating meeting type is not supported.
