Google Assistant SDK Installation Issues

Hello!

Trying to install this integration: Google Assistant SDK - Home Assistant, running into issues on step 11

Installing google-auth-oauthlib[tool] works fine, running it multiple times just writes Requirement already satified a bunch of times.

When running the oAuth command (Windows): google-oauthlib-tool --scope https://www.googleapis.com/auth/assistant-sdk-prototype --scope https://www.googleapis.com/auth/gcm --save --client-secrets %userprofile%\Downloads\client_secret.json, I get the result 'google-oauthlib-tool' is not recognized as an internal or external command, operable program or batch file.

Just updated PIP with C:\Users\x\AppData\Local\Microsoft\WindowsApps\PythonSoftwareFoundation.Python.3.11_qbz5n2kfra8p0\python.exe -m pip install --upgrade pip, and C:\Users\x\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.11_qbz5n2kfra8p0\LocalCache\local-packages\Python311\Scripts is in PATH for both user and global.

Is there something I am missing here?

Thank you!
