getSynchronizeOnStartup

If set to `true`, the SDK will fetch all user conversations from the backend on startup.

If set to `false` the SDK will start faster, but getMyConversations will return empty list and onClientSynchronization will be called with SYNCHRONIZATION_DISABLED.

When set to `false` call getConversation to fetch specific conversation or call synchronizeConversations and wait for onClientSynchronization with COMPLETED to get all user conversations.

The default value is `true`.
