AutoML : Unable to get the Details of Native Models

[ScriptAbility]

We are using Auto ML Client libraries(C# and PHP) for listing the AutoML custom Translation models.
But with the API's

AutoMlClient.ListModels(parent);

$autoMlClient->listModels($formattedParent);

we are only able to list the Legacy models, Native models details are missing from the response. Is there any other API's that can be used to list Native models?

In console GCP suggests to use Cloud Translation API for managing the native models, but in that library, there are no API's to list the models
