    "        options -> The labels for the radio options. Internally, this will be cast to str by default. The first column is chosen for pandas.DataFrame.\n",

    "        format_func -> This function allows you to change how radio options are displayed. It takes the raw option as an argument and outputs the label that should be displayed for that option. The radio's return value is unaffected by this.\n",
    "        \n",
    "        key -> An optional string or int to be used as a unique key for this widget. If omitted, a key will be generated for the widget based on its content. Multiple widgets of same types cannot share the same key.\n",
    "        \n",
    "        help -> An optional tooltip that gets displayed by the button\n",
    "        \n",
    "        on_change -> An optional callback invoked when this radio's value is changed\n",
    "        \n",
    "        args -> An optional tuple of args that can be passed to the callback\n",
    "        \n",
    "        kwargs -> An optional dictionary of kwargs that can be passed to the callback\n",

Once you run the command, the app will automatically open in your default browser."
