Mypy not catching correctly the toml library

[uriii3]

We have a precommit action in our repo. The Mypy library throws an error when we are using the toml library:

path_to_test.py: error: Library stubs not installed for "toml"  [import]
path_to_test.py: note: Hint: "python3 -m pip install types-toml"
path_to_test.py: note: (or run "mypy --install-types" to install all missing stub packages)
path_to_test.py: note: See https://mypy.readthedocs.io/en/stable/running_mypy.html#missing-imports

I've done all the things from Mypy and it seems like it doesn't work, I guess the problem then might come from your side (?). Not sure how can I be more specific (I know I'm not being very detailed).
