Not able to request batch api of GPT 5.2

I have created new api key in project and enabled GPT 5.2 it have chat-completions and responses access for gpt-5.2, but Batch API requests on endpoint fail with:

 Project does not have access to model `gpt-5.2-2025-12-11-batch`

Is there any setting I am missing? Please help me in resolving this.
