Hi, I am trying to extend a pulumi provider resource class to include some properties, something like this:

but, of course I am getting circular promises
```  pulumi:pulumi:Stack (azure-sql-us-prod):
    error: Running program '/workspaces/pulumi/projects/azure-sql/src/index.ts' failed with an unhandled exception:
    &lt;ref *1&gt; TypeError: Cannot set property databaseName of #&lt;AzureNativeSqlDatabase&gt; which has only a getter

      promise: Promise { &lt;rejected&gt; [Circular *1] }
    }```
Is there a correct way/alternative way to do this?

I want to avoid the typical helper/util function to extract those parameters
