Talk app for iOS: multi account

In the Nextcloud Files app for iOS, it supports multiple sign-ins, and I can easily switch between them. However in the Talk app, it seems only a single sign-in is supported.

I use Talk on my personal Nextcloud server, but if my company were to adopt Nextcloud, I would need to receive push notifications, so I would have to make a choice between work messages and personal messages. This would be a problem.
