How to reference parent resource in module in azure bicep?

Question

I am trying to create a service bus and topic (many topics and their subscriptions) with the azure bicep.

I have main bicep like below

param topics array;

resource serviceBusNamespace 'Microsoft.ServiceBus/namespaces@2018-01-01-preview' = {
name: serviceBusNamespaceName
location: location
 sku: {
   name: skuName
 }
}

module topicSubscription './sb_topic.bicep' = [for topic in topics: {
name: 'topicSubscription${topic}'
params: {
topic: topic
  }
}]

module file looks like

resource sbTopics 'Microsoft.ServiceBus/namespaces/topics@2022-01-01-preview' = {
  name: topic.name
  parent: ??
  properties: topic.properties

  resource symbolicname 'subscriptions@2022-01-01-preview' =  [for subscription in topic.subscriptions: {
    name: 'string'
    properties: {}
  }]
}

How can pass the parent serviceBusNamespace resource as parent to the child resource inside the module?

Kindly suggest..

In the module reference the namespace with an 'existing' declaration. Something like this

param namespaceName string

resource serviceBusNamespace 'Microsoft.ServiceBus/namespaces@2018-01-01-preview' existing = {
  name: namespaceName
}

resource sbTopics 'Microsoft.ServiceBus/namespaces/topics@2022-01-01-preview' = {
  name: topic.name
  parent: serviceBusNamespace
  properties: topic.properties

  resource symbolicname 'subscriptions@2022-01-01-preview' =  [for subscription in topic.subscriptions: {
    name: 'string'
    properties: {}
  }]
}
