Deleting a photo sent via the bot's send_photo method.

[orenlab]

Hi there!
I have implemented 2FA authentication in my bot. At one point, the bot will send a QR code for the user to add their account to their 2FA app. For security reasons, I want to delete this QR code after a certain period of time, say 3-4 minutes. How can I best go about doing this?

Use scheduling apps such as apscheduler.

Thanks!

Is this option incorrect?

              msg = self.bot.send_photo(
                    message.chat.id,
                    photo=bot_answer,
                    reply_markup=keyboard,
                    caption=".....",
                    protect_content=True,
                    has_spoiler=True,
                    show_caption_above_media=True
                )
                # Delete message after 3 minutes
                def delete_message():
                    self.bot.delete_message(chat_id=message.chat.id, message_id=msg.message_id)

                threading.Timer(180.0, delete_message).start()

I tried to implement it based on my proposal, it works correctly. Thanks anyway!
