CoIP IPv4 Pool Not Found

[jacido]

I have code that is supposed to allocate an Elastic IP from a shared CoIP IPv4 Pool and then associate it with our EC2 instance. However, when it trys to create the Elastic IP from the CoIP IPv4 Pool, it fails with the following error:

---

Resource handler returned message: "The pool ID 'ipv4pool-coip-0XXXXXXXXXXXXXXXX' does not exist. (Service: Ec2, Status Code: 400, Request ID: 2ae8930c-XXXXXXXXXXXX-XXXXXXXXXXXX)" (RequestToken: c8f6daf4-ebec-cefe-f6ec-6144bdfb8f69, HandlerErrorCode: GeneralServiceException)

Code snippet:

---

    // Create Elastic CoIP Address
    const coIPAddress = new CfnEIP(this, "elasticCoIP", {
        domain: "vpc",
        publicIpv4Pool: props.outpost.coip
    });
    //Associate Elastic CoIP with Edison Instance
    new CfnEIPAssociation(this, "ElasticIpAssociation", {
        instanceId: instance.instanceId,
        allocationId: coIPAddress.attrAllocationId
    });

I tested the process using the AWS CLI and was able to associate the Elastic CoIP by following these steps:

1. Get the CoIP IPv4 Pool ID
2. Allocate an Elastic from the CoIP IPv4 Pool using the Pool ID
3. Associate the CoIP with the EC2 instance.

However, these steps don't seem to be working for when using CDK API's.

Is there more than need to be done in order to have the CoIP IPv4 Pool to be shared from another AWS account?
