`example_labels` does not work for ChatInterface

Describe the bug

Based on the screenshot, when using additional_inputs in ChatInterface and providing example prompts, you must manually include default values for these additional inputs in the examples; otherwise, they will be set to None. However, I dislike the examples being displayed beneath the chatbot and the visibility of the additional input values. After reviewing the documentation, I believe example_labels could replace the example display, showing only the example text within the chatbot. Unfortunately, the variable appears to have no effect.

    history: list,
    var_a: bool,
    var_b: list[str],
    var_c: bool,

    print(var_a, var_b, var_c)
    return "Hello, World!"
