Deploying Hybrid Connection to webapp using bicep - azure

Question

I'm trying to create an Hybrid Connection on a webapp using Bicep.
The documentation, unfortunately, has no descriptions in the properties of RelayServiceConnectionEntityProperties:
https://learn.microsoft.com/en-us/azure/templates/microsoft.web/sites/hybridconnection?tabs=bicep
This is what I tried:
resource webappHcm 'Microsoft.Web/sites/hybridconnection#2021-02-01' = {
name: 'hcm'
parent: webapp
properties: {
entityConnectionString: 'Endpoint=sb://xxxxxxx.servicebus.windows.net/;SharedAccessKeyName=defaultListener;SharedAccessKey=XXXXXXXXXXX;EntityPath=xxxxxxxxxxxxxxx'
entityName: 'xxxxxxxxxxxxxxxxx'
hostname: 'xxxxxxxxxxxxxxxxx.hostname.internal'
port: 12345
// resourceConnectionString: 'string'
// resourceType: 'string'
}
}
However, when I try to deploy, I get this error:
Required parameter EntityName, EntityConnectionString, ResoureType, ResourceConnectionString, Hostname, or BiztalkUri is missing.
I have no idea what to put in resourceConnectionString, resourceType nor biztalkUri.
Any ideas where I can find those, or what am I doing wrong?
Unfortunately, doing it on the Azure Portal manually, and then "Export template", the export doesn't have anything related to the hybrid connection (whether it is in the Webapp, or in the Hybrid Connection itself)

for creating Hybrid-Connection for webs you need to have bicep file like:
param appServiceName string
var cfg = json(loadTextContent('../../bicepConsts.json'))
var hc = cfg.HybridConnection
resource appService 'Microsoft.Web/sites#2021-02-01' existing = {
name: appServiceName
}
var relayId = resourceId(hc.ResourceGroup, 'Microsoft.Relay/namespaces', hc.Namespace)
var connectionId = '${relayId}/hybridConnections/${hc.Name}'
var senderKeyName = 'defaultSender'
var key = listKeys('${connectionId}/authorizationRules/${senderKeyName}', '2017-04-01').primaryKey
resource hybridConnection 'Microsoft.Web/sites/hybridConnectionNamespaces/relays#2021-02-01' = {
name: '${appService.name}/${hc.Namespace}/${hc.Name}'
location: hc.NamespaceLocation
dependsOn: [
appService
]
properties: {
serviceBusNamespace: hc.Namespace
relayName: hc.Name
relayArmUri: connectionId
hostname: hc.Host
port: hc.Port
sendKeyName: senderKeyName
sendKeyValue: key
serviceBusSuffix: '.servicebus.windows.net'
}
}
Where this bicepConsts file contains think like:
{
"..." : "...",
"HybridConnection": {
"ResourceGroup": "resource group of your HybridConnection from Azure",
"Name": "Name of hybrid connection",
"Namespace": "Namespace of hybrid connection",
"NamespaceLocation": "Location (e.g. 'West US 2') of your hybrid connection namespace",
"Host": "Host of your hybrid connection",
"Port": "Port of your hybrid connection AS INTEGER!",
}
}
