---@param unit string 
---@return boolean exists 
---Returns whether a unit exists. A unit "exists" if it can be referenced by the player; e.g. party1 exists if the player is in a party with at least one other member (regardless of whether that member is nearby), target exists if the player has a target, npc exists if the player is currently interacting with an NPC, etc.
---@overload fun(name: string)
function UnitExists(unit, name) end
