How do we backup the custom GPTs

No, according to a forum post (What happens to your custom GPT (that you made) if you stop paying for ChatGPT Plus? And other questions) from OpenAI’s community, if you stop paying for your ChatGPT Plus subscription, the custom GPTs that you made will be deactivated. It’s not specified whether they are deleted, but they will be unshared. Furthermore, you will no longer share in any revenue generated by these GPTs.
