### Ideas for solutions (Optional)

I saw an issue,https://github.com/Comfy-Org/ComfyUI_frontend/issues/1961, which mentioned that it would add proxy address settings and open proxies. But I don't see any settings in the Comfy UI front-end.

I use ComfyUI in Ubuntu 22.03. Where can I set this option? (I need to set the HF mirror address to: https://hf-mirror.com) Thank you.
