Pusher with Laravel Application along Queue Jobs working with QUEUE_DRIVER set to databse in env file instead sync

Laravel Version: 5.6

Can I use pusher for a laraval web application with QUEUE_DRIVER option set to "database" in env file?

Currently, there are some Queue Jobs running with queue connection set to "database" in env file,

I have to implement pusher for notifications, but queue driver connection setting is conflicting with pusher settings.

I do not know why pusher needs to use QUEUE_DRIVER=sync in env file to work properly. I can not set it to sync because queue jobs are running with connection set to "database"

Can anyone help me on this?
