Actually I am using the Chat GPT 4 where Plugins options was working before which was easy to create some flow charts not its not showing in the New Chat.Whether its disabled in any case ?
OpenAI has removed plugins in favor of Custom GPTs as of this month. Hopefully there’s a custom GPT that does what you’re looking for?
