hi! I'm trying to get access to the ID of the 
NodeSecurityGroup
created by 
eks.NewCluster
but the type returned is a 
*SecurityGroupOutput
and I can't figure out how to get the ID output out of it to use with other resources

I'm trying to get it to 
NewVpcEndpoint
, which takes a 
StringArrayInput
for the 
SecurityGroupIds
field and it wasn't clear how to convert it as there's no 
ToStringOutput
method on 
SecurityGroupOutput
and no obvious 
ToStringArray*
function for this
Copy code
./main.go:71:48: cannot use cluster.NodeSecurityGroup (type "<http://github.com/pulumi/pulumi-aws/sdk/v4/go/aws/ec2|github.com/pulumi/pulumi-aws/sdk/v4/go/aws/ec2>".SecurityGroupOutput) as type pulumi.StringInput in slice literal:
        "<http://github.com/pulumi/pulumi-aws/sdk/v4/go/aws/ec2|github.com/pulumi/pulumi-aws/sdk/v4/go/aws/ec2>".SecurityGroupOutput does not implement pulumi.StringInput (missing ToStringOutput method)
I worked around this with
Copy code
// HACK: cluster.NodeSecurityGroup is a SecurityGroupOutput that doesn't have an accessible ID
	nodeSecurityGroupTag := cluster.ToClusterOutput().ApplyT(func(_ *eks.Cluster) string {
		// use ApplyT to build a StringOutput that depends on cluster
		return prefix + "-nodeSecurityGroup"
	}).(pulumi.StringOutput)
	nodeSecurityGroup := ec2.LookupSecurityGroupOutput(ctx, ec2.LookupSecurityGroupOutputArgs{
		Tags: pulumi.StringMap{"Name": nodeSecurityGroupTag},
	})
should I file an issue somewhere describing this use case?
