argocd-k8s-auth aws command dont have flag for region-code

[Ryu-Z]

Summary

we have six eks clusters, and we have a ops eks cluster, deploy argocd in the ops eks cluster.
use an iam role sts assume for other aws accounts role to mange eks cluster

Motivation

my argocd serviceaccount have an iam role for sts assume to other accounts

apiVersion: v1
kind: ServiceAccount
metadata:
  annotations:
    eks.amazonaws.com/role-arn: arn:aws:iam::[aws-account-id]:role/[ops-eks-cluster-role]
  labels:
    app.kubernetes.io/component: repo-server
    app.kubernetes.io/name: argocd-repo-server
    app.kubernetes.io/part-of: argocd
  name: argocd-repo-server
  namespace: argocd

can argocd-k8s-auth aws command have the region-code flag set?
like this

{
  "tlsClientConfig": {
    "insecure": false,
    "caData": "LS0...=="
  },
  "execProviderConfig": {
    "command": "aws",
    "args": [
      "--region",
      "ap-northeast-1",
      "eks",
      "get-token",
      "--cluster-name",
      "[eks-cluster-name]",
      "--role",
      "arn:aws:iam::[aws-account-id]:role/[role-name]"
    ],
    "env": null,
    "apiVersion": "client.authentication.k8s.io/v1beta1",
    "installHint": "aws dont exist"
  }
}

Proposal

https://aws.amazon.com/premiumsupport/knowledge-center/amazon-eks-cluster-access/?nc1=h_ls
i use this docs to configure my eks clusters
i want have a region field in the awsAuthConfig configuration and a sts assume configuration,
this can use the arocd container identity role to aussme other aws role
like this:

{
    ...
    "awsAuthConfig": {
        "region": "us-east-1",
        "clusterName": "[eks-cluster-name]",
        "assumeRoleARN": "arn:aws:iam::[aws-account-id]:role/[role-name]"
    },
    ....
}

Can you show something which indicates that managing clusters in regions other than where Argo CD is not working? I've been able to manage clusters across regions (and accounts) with argocd-k8s-auth without needing to set a region.

Closing for now, if this is something which doesn't work feel free to re-open this issue.
