No "use_drink" is the simple name you need to call for the animation in scripts.

https://docs.larian.game/Osiris/API/SetAnimationOverrideThe specific animations in root are named like
Dwarves_Hero_Female_ABC_Use_Drink_01
Dwarves_Hero_Male_ABC_Use_Drink_01
etc
If you open any of the "hero" entries under VisualSetResource (the double teapot icon in the resource manager) you can use the drop down next to the Play Animation button to scroll through all the various simple named animations. They are alphabetical so scroll to the bottom to find use_drink, use_eat, etc.
