Does this need changelog ?

Nope, just need to test if this works for typing_extensions 4.0.0 since that's the lowest allowed version in the requirements.

[Paillat-dev]

It does work, I will test again and merge master in here

[Dorukyum]

TypedDict has had changes after 4.0.0 (ref), we'd better test both older and newer versions.

[Paillat-dev]

will do
