Is comfyui_colab.ipynb missing Flux ?

[BlohoJo]

Sorry for the dumb question, but is comfyui_colab.ipynb missing Flux models/checkpoints/nodes? Is it possible to add a Flux section?

FLUX is a model, not a node. It is natively supported by the default nodes.
You need to download and add the model yourself.
