The iOS intercom SDK (14.0.6) crashes whenever I try to present it using default present() method or present(.home) method. If I use present(.messages) it works fine. Previous versions of Intercom worked fine. Is this a known issue?

Question

Also tested with all versions from 14.0.0 and they all crash when trying to present the Messenger.It crashes even when launched from the Intercom launcher.Note: the view controllers are loaded from individual XIB files and not from a storyboard. The SDK was installed through Swift SPM. *** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[ setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key chatButton.' The weird thing is that we don't have a HomeHeaderViewController but our button is named 'chatButton' from where we launch intercom. If I rename chatButton to 'helpButton' the message will change to:*** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[ setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key helpButton.'Is there something that I need to do differently? If I use: Intercom.present(.messages) it does not crash..
