Why does mypy ignores argument error with those errors are in a function?

Question

In the following example, Example.__init__ and f_example takes not argument. Thus, mypy is supposed to warn if I try to pass some argument to them. However, when I apply mypy check to the following code, it does not warn nothing. Do I make mistake?

FYI, I also use pyright with vim and pyright warn about these errors as I expected.

class Example:
    a: int
    def __init__(self) -> None:
        self.a = 0

def f_example():
    return None

def test():
    e = Example()
    e2 = Example(1)
    f_example()
    f_example(1)

test()
