LGTM! Just added a question

[fabiorigam]

Why is this command commented?

[freemanzMrojo]

It is because of this issue localstack/localstack#11678 . Basically nowadays we cannot import a custom key into localstack, but once the issue is fixed we should be able to do it with this commented-out line.

The command itself does not break but it does not import anything.
