Create NetApp Storage Pool - SET UP CONNECTIONS NETWORK issue

[tacoma50]

I am using this CREATE-STORAGE-POOL quick start guide:
   https://cloud.google.com/netapp/volumes/docs/get-started/quickstarts/create-storage-pool
At step 8 under CREATE A STORAGE POOL it says:

Under SET UP CONNECTIONS, select the VPC you want to use. If you haven't peered your VPC, click "Set up connection" and complete the following steps:
   a.Enable the "Service networking API"
   b.Click "Use an automatically allocated IP range" or click "Select one or more
      existing IP ranges or create a new one" to manually choose a CIDR.

There is no button here to Enable the Service networking API, but I found the SERVICE-NETWORKING-API and enabled it.
For step 8.b none of those options appear for me to click on. So I am not sure how to continue setting up networking for my storage pool.
Can some one help.

Ultimately once I create this storage pool I will create a 100gb NETAPP VOLUME from that storage pool.
Then I will mount that volume on two of my GCE VMs as a directory called /mySharedData that both VM servers will write to.
