I have left a few comments specific to design and implementation. A more general comment is that none of the tests are updated. We need to update the test classes to verify the modified functionalities.

@mghoneimy thank you for a review. Fixed the comments, but some things are to be discussed, looking forward.

We are very close here. The comments I added are mostly small. I'm trying to figure out why travis builds stopped on build requests too. Once both these things are done, we should be good to go.

Tests are fixed now

Thank you for addressing all the previous comments and fixing the tests!

I think that one comment is was not completely addressed and I think that I found a problem worth looking into before we merge this in.

Can you rebase your branch on the latest updates on master please, I had to replace travis-ci with Github actions to have the tests continue to run.

Thanks for addressing all the comments. I accepted the changes, but again, I still need need you to rebase your changes on master before we can merge the PR.

Great! Thank you.
Yeah, no problem. I've rebased the branch.
Checks were not started, please, run them to ensure everything is fine

Hi, does anyone have an example of how the code should look like with this? As in, when making a query to a GraphQL endpoint with IAM auth.
