Most of the contributors don't have access to this private repo
perhaps we should guard this test in a different way

I faced this issue too. I would like to help to clean it up.
Do you have any suggest approach ?

I'm thinking for these steps that require private key
skip them if certain environmental variable are not present

We can’t run this test locally, or on CI. The only place it can be run is my laptop. Let’s skip this test for everyone.
