Last chat message checking

Hello. Recently (a few days ago) I decided to make a mod containing a procedure that should check the latest chat message for the content of a certain word. If this word is present, the player should be teleported to certain coordinates. But I can't do chat tracking. I looked for information on the Internet and asked AI. Nothing helped. The same problem with the "If the text... contains..." block. I entered a local variable as text, if this local variable contains the required word, then what should happen. But that didn't help either. Can you help me?
