Apptentive iOS SDK clear conversation

Question

Using Apptentive SDK for iOS (https://github.com/apptentive/apptentive-ios).

When a user logs out of my app, I need a way to clear the conversation that is saved by Apptentive.

Have tried:

[[ATConnect sharedConnection] setInitialUserName:@""];
[[ATConnect sharedConnection] removeCustomPersonDataWithKey:@"name"];
