The same private key is working in TypeScript sgid library.

To Reproduce Steps to reproduce the behavior:

1. Follow the python sgid-client tutorial
2. Update the .env file with your sgid project credentials.
3. run the flask application with python -m flask run

Expected behavior The same credentials are used in the Typescript sgid library and it worked there for ts.
