使用Gmail API Python删除标签

Trying to use Gmail API to delete a label.但它似乎不起作用，并在python中触发了insufficient permission错误.这似乎不正确，因为在Google中显示所有权限都已选中.有没有可以申请解决的代码修复，或者是其他什么？

CODE USED TO DELETE LABEL

try:
            target_label_name = "Label_8"
            service = build("gmail", "v1", credentials=creds)
            messages_results = service.users().messages().list(userId="me", labelIds=[target_label_name]).execute()
            messages = messages_results.get("messages", [])
    
            if not messages:
                print(f"No emails found with label: {target_label_name}")
                return
    
            for message in messages:
                # Remove the label from the message
                service.users().messages().modify(userId="me", id=message['id'], body={'removeLabelIds': [target_label_name]}).execute()
                print(f"Label {target_label_name} removed from message {message['id']}.")

Get this error about insufficient permissions个
