This PR

Cleaning up some tech debt associated mentioned in this comment

• Dynamically resolve based on keyword arguments
• I wasn't able to find a configuration that worked on python 3.8/3.9 with mypy. I opted for ignoring the call-arg.
• If we'd prefer not ignore the error and keep positional arguments, feel free to close the PR.

How to test

Standard testing (test, e2e, pre-commit)
