properties from type inference

I am creating using 'zod' for validation and type creation.

```typescript
const accSchema = z.object({
companyName: z.string(),
email: z.string().email(),
demo: z.boolean(),
});

export type IAccountUpdatedPayload = z.infer;

```

using ts-morph, I want to retrieve the properties for IAccountUpdatedPayload, but it does not return any.
I get the TypeAliasDeclaration, but I could not retrieve any valuable information from it

No repository files or tests are named. Start by reproducing the TypeAliasDeclaration case with the shown z.infer example and inspect how ts-morph resolves its type; done should include a defined way to retrieve the inferred account properties, with coverage for the example.
