I am using EKS to run terraform and created service account for aws access, Also I want to get access for of cross account using assume role, created the role in cross account and created new role in primary account with inline policy, and added in terraform as below

provider "aws" {
  region = "us-east-1"
  assume_role {   role_arn = "arn:aws:iam:11111111111:role/atlantis-prod-account"   }
 }
