seems like you need special permissions to rerun from within azure pipelines UI (eg [https://dev.azure.com/nim-lang/Nim/_build/results?buildId=5365&view=results)](https://dev.azure.com/nim-lang/Nim/_build/results?buildId=5365&view=results\)), which I don't have, since it's possible for a PR against my nim fork but not a PR against nim repo.
However I found another way that works just as well: doing it from github UI works perfectly; this is explained in [https://github.com/timotheecour/Nim/issues/211](https://github.com/timotheecour/Nim/issues/211) It should probably be mentioned in docs as I'm sure a lot of ppl are not aware of this and they restart the whole CI (eg via a push or via a close/reopen PR)
