---@param index number The option in the NPC gossip window to select, from 1 to GetNumGossipOptions()
---@param text string|nil Text to include when confirming the selection
---@param confirm boolean|nil true to confirm the selection; false or omitted otherwise
--- Chooses and activates an NPC dialog option. Results may vary according to the gossip option chosen;
--- may end the gossip (firing a GOSSIP_CLOSED event) and start another interaction (firing a
--- MERCHANT_SHOW, TRAINER_SHOW, TAXIMAP_OPENED, or similar event) or may continue the gossip with
--- new text and new options (firing another GOSSIP_SHOW event).
--- Calling this function with only the first argument may cause the GOSSIP_CONFIRM event to fire,
--- indicating that the player needs to provide confirmation (or additional information) before the
--- option will be activated. Confirmation is needed for certain options requiring the character to
--- spend (e.g. when activating Dual Talent Specialization); additional information is needed for
--- options such as those used when redeeming a Loot Card code from the WoW trading card game to
--- receive an in-game item. In either case, the confirmation and additional information can be
--- provided (as by the popup dialog in the default UI) by calling this function again with all
--- three arguments.
