example_labels does not work for ChatInterface

[jamie0725]

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.

    req: gr.Request,
    message: str,
    history: list,
    var_a: bool,
    var_b: list[str],
    var_c: bool,

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

What I want is one of these behaviors:

1. Not required to set the values for additional_inputs in examples, but still use the inputs' default values.
2. Setting the values for additional_inputs in examples is also fine, but don't show their values on the webpage; instead, only show the text part to the user as an example prompt inside the chatbot.

In the end, I want the examples to use the same default values for additional_inputs, and at the same time want the examples to be shown like this:
