VNet Connection "propagate to none" with Bicep

Question

I am attempting to peer vnets together in my virtual hub with a Bicep template. This is what I want to produce, from the point of view of the GUI:

In particular, I cannot see how to set "propagate to none" = Yes with Bicep (or ARM) using the Microsoft.Network/virtualHubs/hubVirtualNetworkConnections resource.

Thanks,
Eric

I was able to figure this out. Essentially, you reference the "noneRouteTable" which is part of the virtual hub. Here is an example "Microsoft.Network/virtualNetworks" resource. (Earlier in the file I defined the vHub, which I called 'vHub' and is named "TestVHub".)

resource vHub_spoke1 'Microsoft.Network/virtualHubs/hubVirtualNetworkConnections@2021-05-01' = {
  name: 'TestVHub-net1'
  parent: vHub
  properties: {
    remoteVirtualNetwork: {
      id: spoke1.id
    }
    allowHubToRemoteVnetTransit: true
    allowRemoteVnetToUseHubVnetGateways: true
    enableInternetSecurity: true
    routingConfiguration: {
      associatedRouteTable: {
        id:  resourceId('Microsoft.Network/virtualHubs/hubRouteTables', 'TestVHub', 'defaultRouteTable')
      }
      propagatedRouteTables: {
        ids: [
          {
            id: resourceId('Microsoft.Network/virtualHubs/hubRouteTables', 'TestVHub', 'noneRouteTable')
          }
        ]
        labels: [
          'none'
        ]
      }
    }
  }
}
