How to know and set the resample method of pipewire-pulse?

I just noticed that there was a replacement of pulseaudio released,it has lower latency output, lower CPU usage, it is just better, but I have few questions, I used to set the resample method to soxr-hq for better audio quality, but I use pactl list sink-inputs to check what resample method it is using, it returns PipeWire to me.

What exactly is the PipeWire resample method?
Can I easily write the resample method in config file like PulseAudio before?

By the way, do I need to install pipewire-media-session if pipewire-pulse is installed?

I saw that few minutes ago, thanks.

I still wonder what algorithm it is using though.

...PipeWire uses its own resampling algorithm called Spa
