CLEO Help Delete/block chat line

[Angel9]

how to block or automatically delete a line in the chat when they text appears?
I tried the script from this thread but it doesn't work : https://ugbase.eu/threads/can-i-delete-text-from-chat.21714/
An example message that is not always the same, only the beginning is the same

{FFAF00}[ADA] {FFFFFF}KOUE {FFAF00}Jack_Castellano: {FFFFFF} Sell car
{FFAF00}[ADA] {FFFFFF}KOUE {FFAF00}Mike_Johns: {FFFFFF} Sell house
