Making an NPC walk using a Trigger

How do I make an NPC (Fast Zombie in particular) walk to a certain point once the player touches the trigger? Any help would be appreciated, I can’t find anything on google so please help if you can.

ai_scipted_sequence or some other ai_ node.

Ai_rally (something like that) or make it follow a path.

Ai_scriptedschedule or ai_scripted_schedule or something.
