How to use the jsii._embedded function in jsii

            paths = [
                self._ctx_stack.enter_context(
                    importlib_resources.path(jsii._embedded.jsii, f)

            tmpdir = self._ctx_stack.enter_context(tempfile.TemporaryDirectory())

            for path, filename in zip(paths, filenames):
                with open(path, "wb") as fp:

        # Ensure that our jsii-runtime.js is the first entry in our paths, and that all
        # of our paths, are in a commmon directory, and we didn't get them split into
        # multiple directories somehow.

        assert os.path.commonpath(paths) == os.path.dirname(paths[0])

        # Return our first path, which should be the path for jsii-runtime.js
        return str(paths[0])
