Don't know if this is just me, a bug or by design but it doesn't look like this works with item hotkeys. I have a few items that come with hotkeys that trigger animations on vtube studio but the hotkeys don't work unless i load the item as an actual model. My mixitup and bikubot can both use the item keys no problem so it seems to be just stream deck that can't currently which is a shame. I think the only way around it is by assigning actual keys but that kind of defeats the purpose of the integrated app. Might be something worth looking into.
