[Python] Use importlib.resources for files inside the top level parent module

I want to load a file from my python module using importlib.resources (see also this question). If the file is inside a submodule, this is straight forward (run using python -m, see here):

import importlib.resources
from . import submodule

print(importlib.resources.files(submodule).joinpath("file.txt").read_bytes())


For files in the same module, it is possible to use __package__:

import importlib.resources

print(importlib.resources.files(__package__).joinpath("file.txt").read_bytes())


However, I cannot get this approach to work for files inside the top level module, if I want to access them from a submodule:

module
├── file.txt
├── __init__.py
└── submodule
├── __init__.py
└── submodule_script.py


import importlib.resources

from ... import module # ImportError: attempted relative import beyond top-level package
import .. as module # SyntaxError: invalid syntax
from .. import . as module # SyntaxError: invalid syntax

print(importlib.resources.files(module).joinpath("file.txt").read_bytes())


How can I obtain an import-like reference to the top level module location, such that importlib.resources can understand it?
