Some ideas: we can create the logstream if is not set.

Some ideas: we can create the logstream if is not set.

Ok, that's a good idea. If falcosidekick can't do it (lack of IAM rights), the error should be explicit

[cpanato]

@Issif ok, give me a minute to refactor this code or do you prefer in a followup?

Better to do all here, as it's a new Output

[cpanato]
