Deployment of CosmosDB Account takes a lot of time

The bicep deployment time of the bicep file below is really high (westeurope). Even if it's already exists. Can this be investigated?

```
param location string
param cosmosDbAccountName string
param accountOfferType string

var locations = [
{
locationName: location
failoverPriority: 0
isZoneRedundant: false
}
]

resource cosmosDbAccount 'Microsoft.DocumentDB/databaseAccounts@2023-04-15' = {
location: location
name: cosmosDbAccountName
kind: 'GlobalDocumentDB'
properties: {
disableKeyBasedMetadataWriteAccess: true
databaseAccountOfferType: 'Standard'
consistencyPolicy: {
defaultConsistencyLevel: 'Session'
maxIntervalInSeconds: 5
maxStalenessPrefix: 100
}
backupPolicy: {
type: 'Continuous'
}
locations: locations
enableAutomaticFailover: true
}
tags: {
defaultExperience: 'DocumentDB'
}
}
```

Start by reproducing the deployment using the supplied Bicep resource declaration for Microsoft.DocumentDB/databaseAccounts@2023-04-15 in westeurope, including an already-existing account. Measure where the deployment spends time and investigate the Azure resource behavior; done means the cause is identified and a concrete fix or documented limitation is established.
