Get target selector for entity which was last interacted with?

I'm trying to use an advancement to detect a player interacting with an entity, so I can trigger a function which affects that entity's data, via the data command. To do this, I need the entity's UUID, or maybe a target selector which can select the last-interacted-with entity. How can I do this? Is there a a way to get additional information from the trigger? "criteria": { "sole_criterion": { "trigger": "minecraft:player_interacted_with_entity", "conditions": { "item": { "items": [ "minecraft:potion" ], "potion": "minecraft:thick" }, "entity": { "type": "minecraft:villager" } } } }
