Bluetooth headset does not show up in the sinks list

I edited the /etc/pipewire/pipewire.conf and added -e bluez5 to exec /usr/bin/pipewire-media-session line. When I connect the bluetooth headset (Sennheiser HD 350BT), it does not show up in the sinks list (at least as pactl lists them, I don't know how to list sinks with native pipewire tools). So I cannot switch to my headset, it continues playing via laptop speaker.
