To bulk download of my snap history I used something like this.
export SNAP=yakshaveinc
export FROM=1
export TO=74
snapcraft export-login --snaps=$SNAP --acls=package_access ysi.download
for i in $(seq $FROM $TO); do UBUNTU_STORE_AUTH_DATA_FILENAME=ysi.download snap download $SNAP --target-directory=ysi --revision=$i; done
rm ysi.download
