Thanks for stopping by to let us know something could be better!

#### Environment details

- OS:
- Node.js version: v20.14.0
- npm version: 10.7.0
- `googleapis` version: 118.0.0

#### Steps to reproduce

1. Go to the rest API > https://cloud.google.com/resource-manager/reference/rest/v1/projects/setIamPolicy
2. Enter your in the resources
3. Add the request body including changes in both `auditConfigs` and `bindings`. Make sure we add `exemptedMembers` to the config with service as `allServices`
4. The changes in `bindings` will be updated but the changes in `auditConfigs` will not be updated

When we try to update `auditConfigs` using the `projects.setIamPolicy` API any change is not reflected however when using the console or the CLI (`gcloud projects set-iam-policy parker-aac policy.json` where we have a file policy.json with the updated request body) we are able to update it especially when changing the `exemptedMembers` parameter.

We do have a documentation supporting this > https://cloud.google.com/resource-manager/reference/rest/v1/projects/setIamPolicy
Since we are able to update it using the CLI or from the console we should be able to do with the API as well.
Also the API is able to update the `bindings` then why not the `auditConfigs`

Making sure to follow these steps will guarantee the quickest resolution possible.

Thanks!
