CallKit maximumCallGroups increase

Hi everyone,

I'm trying to use callkit and wanted to increase the number calls that callkit provide. In the CXProviderConfiguration, there is property called maximumCallGroups. I tried setting it to 5 but it seems not working. I wonder if there is another setup I needed to do in order to apply. The application I'm working on is a voip app and usually voip apps handles multiple calls so if anyone have some experience or knowledge regarding it please let me know thank you.
