OpenAI Free Trial is Expired or inactive issue

Even though I am a Chatgpt plus subscriber, I get this error when I enter the API Key in Google Sheets. How can I solve this problem?

Screenshot by Lightshot thats my issue. Anyone can help?

ChatGPT Plus is not related to the OpenAI API, they are different products. You have to pay for API requests separately from ChatGPT Plus.
