Not working?
- If the button does not work, sign in to ChatGPT and open chatgpt.com/plugins in your browser.
- If the Add button is missing, turn on Developer mode under Settings → Security and login.
- If you cannot select Monaio business with @, find it in your personal plugins and install it.
Access to custom connections depends on your account, plan and workspace rules. Monaio does not itself grant access to ChatGPT features. Read more in OpenAI’s documentation.
