Team, I had created new CosmosDB account in Azure portal with a container contains list of collection items. I am able to access Container details in power shell script.
How to list collection items or show specific collection item using partition key using power shell script
Power shell Script :
Get-AzResource -ResourceType "Microsoft.DocumentDB/databaseAccounts/sqlDatabases/containers" -ApiVersion "2020-03-01" -ResourceGroupName "testRG" -Name "cosmosaccount1/database1/containercollection1"
