Web Messenger reload on Single Page Application

Hi,
A client want to change the messenger deployment (Have another messenger configuration) regarding certain actions on a single page application.
As the webpage doesn't reload, the CXBus stay connected and doesn't allow us to subscribe to a new deployement id.
Do you know how we can proceed to make this working ?
Of course with a page reload it's working but it's not the desired behaviour.

Thanks,
Cédric
