Ui/message host implementation changed from window.openai.sendFollowUpMessage

With the switch to the MCP App bridge, the implementation of the follow Up Message has changed on chatGPT (compared to the previous window.openai.sendFollowUpMessage). The message is now visible in the chat where it wasn’t before. This might be by design but is a UX regression, if the app tries to pass some hard to digest content to the model for summarization. Exemple here: (follows up a long list of questions/answers) We have designed a lot of apps with this invisible followUpMessage in mind. Is this intended ? If so we are losing a nice UX feature for MCP apps.
