You can, if you use a single SendBird application for all of those apps. In other words, you would have to have one application in your SendBird Dashboard, with its application ID shared among multiple apps.

If your apps are designed to be installed on the same device, you can upload multiple push configuration certificates from our Dashboard in order to manage push notifications.
