How to get instance ID of created EC2 instance

Trying to get the instance ID of an EC2 instance created by CF (generated by AWS CDK), this used to work in at least v0.28:

    const natInstance1 = new CfnInstance(this, 'NatInstance1', {
      imageId: NAT_AMI_ID,
      instanceType: NAT_INSTANCE_TYPE,
      subnetId: vpc.publicSubnets[0].subnetId,
      keyName: NAT_SSH_KEY,
      sourceDestCheck: false,
      securityGroupIds: [ 
        publicSecurityGroup.securityGroupId
      ]
    });

    new ec2.CfnEIPAssociation(this, 'NatEip1', {
      eip: NAT_EIP_POOL[0],
      instanceId: natInstance1.instanceId
    });

This no longer works in v0.37.0, get error: Property 'instanceId' does not exist on type 'CfnInstance'.ts(2339)
