// Turns on Amazon Web Services Resource Explorer in the Amazon Web Services
// Region in which you called this operation by creating an index. Resource
// Explorer begins discovering the resources in this Region and stores the details
// about the resources in the index so that they can be queried by using the Search
// operation. You can create only one index in a Region. This operation creates
// only a local index. To promote the local index in one Amazon Web Services Region
// into the aggregator index for the Amazon Web Services account, use the
// UpdateIndexType operation. For more information, see Turning on cross-Region
// search by creating an aggregator index (https://docs.aws.amazon.com/resource-explorer/latest/userguide/manage-aggregator-region.html)
// in the Amazon Web Services Resource Explorer User Guide. For more details about
// what happens when you turn on Resource Explorer in an Amazon Web Services
// Region, see Turn on Resource Explorer to index your resources in an Amazon Web
// Services Region (https://docs.aws.amazon.com/resource-explorer/latest/userguide/manage-service-activate.html)
// in the Amazon Web Services Resource Explorer User Guide. If this is the first
// Amazon Web Services Region in which you've created an index for Resource
// Explorer, then this operation also creates a service-linked role (https://docs.aws.amazon.com/resource-explorer/latest/userguide/security_iam_service-linked-roles.html)
// in your Amazon Web Services account that allows Resource Explorer to enumerate
// your resources to populate the index.
//   - Action: resource-explorer-2:CreateIndex Resource: The ARN of the index (as
//     it will exist after the operation completes) in the Amazon Web Services Region
//     and account in which you're trying to create the index. Use the wildcard
//     character ( * ) at the end of the string to match the eventual UUID. For
//     example, the following Resource element restricts the role or user to creating
//     an index in only the us-east-2 Region of the specified account. "Resource":
//     "arn:aws:resource-explorer-2:us-west-2:<account-id>:index/*" Alternatively,
//     you can use "Resource": "*" to allow the role or user to create an index in
//     any Region.
//   - Action: iam:CreateServiceLinkedRole Resource: No specific resource (*). This
//     permission is required only the first time you create an index to turn on
//     Resource Explorer in the account. Resource Explorer uses this to create the
//     service-linked role needed to index the resources in your account (https://docs.aws.amazon.com/resource-explorer/latest/userguide/security_iam_service-linked-roles.html)
//     . Resource Explorer uses the same service-linked role for all additional indexes
//     you create afterwards.
