Describe the bug
when overriding the userAgent prop for SessionManager
const userAgent = new UserAgent(userAgentOptions); const sessionManager = new SessionManager(server); sessionManager.userAgent = userAgent; sessionManager.delegate = { onCallCreated: () => {console.log('onCallCreated')}, } as SessionManagerDelegate;

the onCallCreated won't be invoked

To Reproduce (if possible)
const userAgent = new UserAgent(userAgentOptions); const sessionManager = new SessionManager(server); sessionManager.userAgent = userAgent; sessionManager.delegate = { onCallCreated: () => {console.log('onCallCreated')}, } as SessionManagerDelegate;

Expected behavior
that the onCallCreated function will be invoked

Observed behavior
onCallCreated won't be invoked no matter what

Environment Information
All
