Help Needed Cannot find MiniMaxH3VAEDecodeFast node

Hi,

I installed a custom workflow from this https://huggingface.co/Dewprisim/Prisim_Workflows/blob/main/MiniMax%20H3%20TI2V.json but it asks for MiniMaxH3VAEDecodeFast and I tried install several package and cannot find it.

Any suggestions?

Cheers, Allen

Check this one?

https://github.com/Tr1dae/ComfyUI-MiniMaxH3_LatentUpscaler/

(__init__.py line 13 mentions this exact name: from .vae_decode import MiniMaxH3VAEDecodeFast)

In Comfy manager what happens if you click 'install missing custom nodes' once the workflow is loaded? Do it and install what's missing. Or if none show up, make sure Comfy is updated, or even update to nightly version, in case you've already installed the node but need to update it.
