I need some help Creating a Node with a UI Display

[lord-lethris]

(Sorry if this is the wrong place to post...)

I need some help - Im trying to learn how to add a UI display to my ComfyUI node, but no matter what I do, there is no display 😦

can anyone help me understand what I've done wrong

here is what I tried:

    @classmethod
    def INPUT_TYPES(cls):
        return {
            "required": {
                "dummy_input": ("STRING", {"default": "Test input"}),
            },
        }

    RETURN_TYPES = ("STRING",)
    RETURN_NAMES = ("output_text",)
    FUNCTION = "process"
    CATEGORY = "utils"
    OUTPUT_NODE = True  # Make sure this is set

    def process(self, dummy_input):
        ui_text_lines = [
            "Hello from TestUiNode!",
            f"Your input was: {dummy_input}",
            "This text is displayed inside the node UI panel."
        ]
        output_str = "\n".join(ui_text_lines)

        return {
            "ui": {"text": ui_text_lines},
            "result": (output_str,)
        }```
