Cannot create channel using hlf channel generate command

[OptimusPrimo11]

What happened?

I try to create a channel with the hlf channel generate --outpu flag but it seems that an error of : unknown flag: --output appear. Then by switching the order of the flags to --name first, still it shows error : unknown flag: --name.

Next, I run the kubectl hlf channel --help
Output : Usage:
hlf channel [command]

Available Commands:
inspect
top
update

Flags:
-h, --help help for channel

So, not "generate" exist.

What am I missing here? Please help.

What did you expect to happen?

A channel file with the filename specified in the --output flag which contains the 2 OrgMSP & 1 OrdererMSP in the channel name given in the --name flag.

How can we reproduce it (as minimally and precisely as possible)?

kubectl hlf channel generate --output=testchannel.block --name=testchannel --organizations Org1MSP --organizations Org2MSP --ordererOrganizations OrdererMSP

Anything else we need to know?
