i run this code for wordpress. basicly just need the clips to show on wordpress. but instead i get the error code: HTTP response code: 400. Response: {“status”:400,”message”:”invalid scope requested: ‘clips:read’”} for this code. im not sure where im doing things wrong here.

if anyone have suggestion please feel free to respond. i cant seem to find any solutions online either

i tried mostly what i could find, yes i did generate the code with help of chatgpt. i dont know if the scope read is changed for twitch but i couldnt find it there aswell.
