Docs say:

• The [ProducesResponseType] attribute's Type property can be excluded. For example, [ProducesResponseType(200, Type = typeof(Product))] is simplified to [ProducesResponseType(200)]. The action's expected return type is instead inferred from the T in ActionResult<T>.

Does produced type inference work exclusively for ActionResult<T> or is there any convention, so I can create my own result type, and OpenApi doc generator will be able to infer the produced type?

I want to write:

Task<ApiResult<T>> Action() {} 

but the actual shape of the output is the following record:

public sealed Result<T>(bool isSuccess, T? result, string[] errors);

and I want swagger to show the correct shape of the result without the need to explicitly write the type.
