there is a package test-commerce-sdk-react in the monorepo that you could use to test the new changes easily.

1. npm run build in commerce-sdk-react
2. cd ../test-commerce-sdk-react && npm start
3. add a new page in the test project to call your new hook

I also tested the changes using test-commerce-react-sdk and it's working.

The code looks like what we have in our other existing hooks so it's LGTM
