@bartholdbos thanks for raising this PR. The change looks good, but unit tests are currently failing. It looks like we might require a mock for getAuthProvider with the relocation of the dispatch to fetch the driver.

@rak-phillip I'm not used to javascript and testing in javascript but I think I have passing unit tests now, if you have any review points please let me know
