Hi vis bharti,
Welcome to Microsoft Q&A,
As you mentioned, you need to connect an Azure subscription to your account. Since you have a free trial account, please check under subscription you will see a free trial subscription ID.
If you don't find one, search for Microsoft Entra in the search bar, which will show the
Tenant ID.
You can use this to establish the service connection to Azure using ARM (Azure Resource Manager).
