Thanks @bradkwadsworth-mw, I left a comment and could you please note the following in the description of your PRs?

• The issue you mentioned in the fixes section will be closed with the merge of this PR. I think this PR does not fully cover the issue(Configure remaining GCP resources without testing #13). So can you fix the fixes part? For instance, you can add the list of resources you have configured here, and remove the Fixes section.
• As I mentioned in the comment, can you be more clear on how it was tested?

And I'm also worried about adding these resources because of this issue. I need to discuss this with the team and we can continue.

Hi @bradkwadsworth-mw,

I discussed this PR with the team and as I mentioned above there is an issue with adding *_iam_binding resources. As mentioned in the issue, there is an incompatibility with using *_iam_member, *_iam_binding, and *_iam_policy resources together. The *_iam_member resources have been tested and added to the v1beta1 version, if you cannot do with *_iam_member what you can do with *_iam_binding, please leave a comment to the issue. That's why I'm closing this PR for now.

Related issue, feel free to comment, thank you!
