Can’t undo the image mode from my conversation

Hi guys,
I have a big and important discussion with Gemini, and during this conversation, I asked it to create an image, picking the image model in the bottom of the discussion.
Everything went well, but now i can't remove the image creator. When i want to go back on the deep research or an other thing, it tells me i have to create an other conversation. So I will lose everything i've done with this one 🙁
Anyone have an idea of how to fix this without losing everything ?
