Install sns-cli

So I’m following the instructions for launching an SNS with Testflight:

https://internetcomputer.org/docs/current/developer-docs/integrations/sns/testing/testing-on-mainnet#overview

A prerequestit is to have installed the SNS_TESTING_INSTANCE bash which I’ve done from here:

and can load:

So I guess I’m wondering is it in here I need to use the sns & sns-cli instructions:

if so I’m not sure how I install those… if you can guide me in the right direction that would be great

Are you wondering about the dfx sns command? You can install that with dfx extension install sns

the sns-cli command here

doesn’t work with just the sns command

@mraszyk can you take a look, please, since you’re much more up to date with the topic than me?
