iOS CalKit: How many calls can be grouped with CXSetGroupCallAction

Hi,


Using iOS CallkIt VoIP API on iOS 10.

THe API for CXSetGroupCallAction allows specifying a call UUID and another UUID of a call to be grouped with.

THis suggests only two calls are allowed in a group. Is this the case or are more calls allowed in a group ie 3+.


Thanks
