Thanks for the PR. I left a few comments. There's currently one PEP8 issue that would also require your attention. You can check locally by doing pip install pre-commit to install pre-commit, pre-commit installto install all packages required to run the checks (flake8 etc) and finallypre-commit run` to do the checks.
