I'm trying to use a custom Shared VPC from another VPC project for a Notebook Instance in the /community/modules/compute/notebook module.

After reviewing the code, it appears that this use case is not currently supported:

https://github.com/GoogleCloudPlatform/cluster-toolkit/blob/main/community/modules/compute/notebook/main.tf
https://registry.terraform.io/providers/hashicorp/google/latest/docs/resources/workbench_instance#nested_gce_setup_network_interfaces

Is there currently a way to achieve this? If not, I'd be happy to contribute to the development of this feature.
