That doesn't make sense. The system and session bus are not
interchangeable, they have different services available etc. If an app
wants the session bus, you have to give it the session bus.

Read "man dbus-launch" (I just made the error message for no session bus
suggest this man page) also "man dbus-daemon"

Sometimes you can just give an app its own private session bus, like:

 "dbus-launch epiphany"

which will launch epiphany and also a session bus that only epiphany
will use; but, really this is kind of nonsensical, though it happens to
work for epiphany at the moment.
