How to make a shopping cart for a telegram bot?

Question

Python

I have a bot that should show a product at the click of a button, namely its Image, name and price. I seem to understand what is needed through the database, and chose SQLite3 for this, and even wrote this database, but I don’t understand what to do next (

@bot.callback_query_handler(func = lambda call: True)
def callback(call):
      if call.data == 'catalog':
        kb = types.InlineKeyboardMarkup(row_width=2)
        item1 = types.InlineKeyboardButton('Эквадорская роза', callback_data='Ecuador')
        kb.add(item1)
      elif call.data == 'Ecuador':
        kb = types.InlineKeyboardMarkup(row_width=1)
        item2 = types.InlineKeyboardButton('Добавить в корзину',callback_data = 'add_cart')
        item1= types.InlineKeyboardButton('Назад',callback_data='bac')
        kb.add(item2,item1)
        bot.edit_message_text(chat_id = call.message.chat.id,message_id=call.message.message_id,
    text = 'описание цветка',reply_markup=kb)

(sorry if the code is not very 'beautiful')
here is a piece of the database:

import sqlite3 as sq
conn = sq.connect('coc.db')
cur = conn.cursor()

cur.execute("""CREATE TABLE IF NOT EXISTS Ecuador0(position TEXT,price TEXT,image BLOB)""")

Ecuador0= [('Херц  50 см','44,200','image'),
('Хот спот 80 см','50,000','image'),
('Хот Эксплоер 60 см','36,000','image'),
('Хот Эксплоер 70 см','39,600','image'), ........
