@andig would you mind reviewing?

I am completely puzzled by the issue reported by golangci-lint.
It is clearly a false positive, but I don't understand why the same flow works locally when executed via act.

Just dont use dot imports?

That's of course one way to solve this. However the dot import style is also used by the other tests in the project, and mores this is also how the authors of convey show this in their docs. At the end of the day, the code style part for sure is arguable. What's more odd though is that the linter claims an unused import, although that's incorrect. But I will cut my losses here, and just adjust accordingly.
