Feature request: auto disconnect from Colab

[chinaexpert1A]

Not sure if this is the place to put this, but I was running my initial experiments on premium GPUs at Colab and since Giffusion is a Gradio app it does not disconnect when idle. It finished a rather large animation and I forgot to disconnect it a couple times, eating up all my credits, a very expensive mistake. It would be great if there was a way to get Gradio to talk to the notebook to disconnect after say 20 minutes or a half an hour of inactivity. Thanks
