How to respond to the user after clicking on the button?

Question

Python

I'm trying to make a system of applications.
The user fills out an application - sends it to the administrator.
The administrator must accept or reject the application using inline buttons, and the user, in turn, must receive an answer about the verdict of his application.
Conditional code:

...
murkup_inline = types.InlineKeyboardMarkup()
item_accept = types.InlineKeyboardButton(text='принять', callback_data='accept')
item_decline = types.InlineKeyboardButton(text='отклонить', callback_data='decline')
murkup_inline.add(item_accept, item_decline)
client.send_message(config.admin_id), 'имя, фамиля, логин, пароль', reply_markup=murkup_inline)

@client.callback_query_handler(func=lambda call: True)
def answer(call):
    if call.data == 'accept':
        pass #Как отправить ответ пользователю?
    elif call.data == 'decline':
        pass #Как отправить ответ пользователю?
