This looks pretty good to me honestly, nice!

@logan-markewich If the fixes look alright can we get the github actions going? It seems to stuck at "waiting for status to be reported", not sure if a maintainer permission is required here

@jisonZ yea first-time maintainers require manually trigger of the actions. A little annoying, but once this merges, future PRs for you will run automatically :)
