Vendor dependencies

[Michael]

Hi, im new in ansible and ansible developing. Now im trying to develop own collection and I wanna bring typing annotations. Some of them require  typing-extensions. I've created a folder _vendor in plugins, and import typing-extensions using relative import
from ..vendor.typing_extensions ...
but got ModuleNotFoundError: No module named name.collection._vendor

but in tarball _vendor module exists. Whats wrong?
