Gst-python with cerbero build. Not found after packaging

I successfully built gstreamer finally with these commands however inside a shell environment gi module is missing. What package requires to be built to get gst-python ?

./cerbero-uninstalled -t -v alsa,pulse,python,gi,optimization,rust,v4l2,rpi,nox11,nocdparanoia package --jobs=4 gstreamer-1.0-core
./cerbero-uninstalled -t -v alsa,pulse,python,gi,optimization,rust,v4l2,rpi,nox11,nocdparanoia package --jobs=4 gstreamer-1.0-net
./cerbero-uninstalled -t -v alsa,pulse,python,gi,optimization,rust,v4l2,rpi,nox11,nocdparanoia package --jobs=4 gstreamer-1.0-playback
./cerbero-uninstalled -t -v alsa,pulse,python,gi,optimization,rust,v4l2,rpi,nox11,nocdparanoia package --jobs=4 base-system-1.0

There’s a cerbero MR here which sounds like it could be related/useful: Add pygobject support (!113) · Merge requests · GStreamer / cerbero · GitLab
