# The 'Button' component triggers the action. In Gradio 4.5.0, components are more streamlined,
# and you might not need to specify the input component type as explicitly.
# Here, the button is directly linked to the action function.
# Note: Unlike previous versions, if your function expects an argument from an input component,
# you must ensure the function can accept it, even if the input is not used.
# Hence, the dummy parameter in 'generate_random_number' function.
