main.py install fdroidpriv not working

[mid-kid]

$ sudo ./env/bin/python3 main.py install fdroidpriv
usage: main.py install [-h] [-c CA_CERT_FILE]
                       {gapps,microg,libndk,libhoudini,magisk,mitm,smartdock,widevine}
                       [{gapps,microg,libndk,libhoudini,magisk,mitm,smartdock,widevine} ...]
main.py install: error: argument app: invalid choice: 'fdroidpriv' (choose from 'gapps', 'microg', 'libndk', 'libhoudini', 'magisk', 'mitm', 'smartdock', 'widevine')

I think it should be possible to install fdroidpriv like this.
