How to set the inline keyboard in Telegram chatbot to other function in python-telegram-bot?

Question

I am building a Telegram chatbot with python-telegram-bot package with inline keyboard that to link to the searching parts. I am not familiar with inline keyboard. At the moment in some way I figure out I need to separate to a function to trigger the keyboard, a function to get the inline keyboard reply and a function to run the searching.

For the function to trigger the keyboard, I figure out as follow:

def refSearch_handler(update, context):
    reply_markup = InlineKeyboardMarkup([[
        InlineKeyboardButton("Search by name", callback_data="search_name"),
        InlineKeyboardButton("Search by function", callback_data="search_function")]])

    bot.send_message(update.message.chat.id, "Please select:", reply_to_message_id = update.message.message_id,
                 reply_markup = reply_markup)

For the function to get the reply from inline keyboard and lead the user to input keyword, I figure out as follow:

def getClickButtonData(update, context):

    if update.callback_query.data == "search_name":
        update.callback_query.edit_message_text("Please input the name: ")

    if update.callback_query.data == "search_function":
        update.callback_query.edit_message_text("Please input the keyword of the function: ")

I know I need to add a conversation hander with the states which is something like below (this is from the demo of the python-telegram-bot package) and I think I should put it in the main() with other dispatchers:

conv_handler = ConversationHandler(
    entry_points=[CommandHandler('start', start)],

    states={
        CHOOSING: [MessageHandler(Filters.regex('^(Age|Favourite colour|Number of siblings)$'),
                                  regular_choice),
                   MessageHandler(Filters.regex('^Something else...$'),
                                  custom_choice)
                   ],

        TYPING_CHOICE: [MessageHandler(Filters.text,
                                       regular_choice)
                        ],

        TYPING_REPLY: [MessageHandler(Filters.text,
                                      received_information),
                       ],
    },

    fallbacks=[MessageHandler(Filters.regex('^Done$'), done)]
)

But I can't figure out how to set up the conv_handler so to point to the inline keyboard and link to the searching function? Just wonder if anyone has experience can guide me?

Many thanks!

I'm not sure if this is what u want but;

Imagine this is your bot:

def bot(update: Update, context: CallbackContext) -> None:

update.message.reply_text("Beginning of inline keyboard")

keyboard = [
    [
        InlineKeyboardButton("Button 1", callback_data='1'),
        InlineKeyboardButton("Button 2", callback_data='2'),
    ]
]

reply_markup = InlineKeyboardMarkup(keyboard)
update.message.reply_text("Replying to text", reply_markup=reply_markup)

Your button function should look like this:

def button(update: Update, context: CallbackContext) -> None:
    query = update.callback_query
    query.answer()
    
    # This will define which button the user tapped on (from what you assigned to "callback_data". As I assigned them "1" and "2"):
    choice = query.data
    
    # Now u can define what choice ("callback_data") do what like this:
    if choose == '1':
        func1()

    if choose == '2':
        func2()

And in your main function where you start your bot, you should add these:

updater.dispatcher.add_handler(MessageHandler(Filters.text & ~Filters.command, bot))
updater.dispatcher.add_handler(CallbackQueryHandler(button))
