How do I make a command that makes clear the chatlog

hi, i want to make a command that clears all the log... I made the condition but i don't know what actions should I put

if you're using a spritefont or text which you're appending to, just set the text to "" which means 'empty string'

i tried that before but it didnt work, xD, i dont know how it worked now... thank u anyway
