How to import g1v1 key into gcli vault and use them in v2s

I am preparing Astroport.TWO To do so, I need to map basic jaklis fonctionnalities on gcli.

${MY_PATH}/jaklis/jaklis.py -k ${PENDINGDIR}/${MOATS}.key pay -a ${AMOUNT} -p ${G1PUB} -c "${COMMENT}"

I try to use "sec" part of dunikey for a vault import with no success

gcli vault import -S seed 3mukJUmyDTtcAyQv9Aw5QCL2vPRGrumSxhdE5qwzRTDQL1rnRq596QryJ4sUXvKGufxdKDAxWxDLDexQVDT2Tptc
error: unexpected argument '3mukJUmyDTtcAyQv9Aw5QCL2vPRGrumSxhdE5qwzRTDQL1rnRq596QryJ4sUXvKGufxdKDAxWxDLDexQVDT2Tptc' found

What would be the right commands ?

thanks
