I have to make a telegram bot, but I'm only provided with uno R3. is there any chance i can make it? I've looked everywhere but only the library for the esp board I found.
The Telegram server only accepts connections with SSL (on port 443).
This board does not have sufficient resources to handle an SSL connection.
First of all, the Telegram is a network service, but Uno R3 doesn't have a network interface.

You could add a ethernet-modul for a copper-wired network-connection.
Though I have no experience if the libraries for ethernet-moduls can handle SSL.
As the Arduino Uno R3 has zero network capabilities you would have to add any kind of network ethernet or WIfI-module to your arduino Uno to make it work.
But then everything will be cheaper if you use a ESP8266 straight-forward.
ESP8266 D1 miniboards start at $2.
What are you reasons that you want to stick so hard with an arduino uno?

I know it would be simpler if I use ESP boards, but i was only provided uno R3 by my boss, i have suggested to upgrade to esp32 but he refused. I have even proved him with my personal device but it doesn't change anything.
There is no way to get a pure Arduino R3 connected to the internet.
If your boss has a computer (with windows) running permanently you could build something over the serial interface of the arduino and let do the PC the internet-connection.
I have no idea what kind of person your boss is. You have to think carefully about how to talk to your boss.
As I have nothing to do with your boss. I can talk very clear
Your boss has not the smallest knowledge about microcontrollers I guess not much knowledge about technology at all but still wants to tell his experts on how to realise
a highly technology based functionality.
Well boss if you know it so precise:
Do it yourself ! If you need to ask, ask the many many experts on the arduino-forum how you do it with an arduino Uno R3.
Another idea would be to indeed use an Arduino Uno R3 connected (or not connected ) to am ESP32 for which you claim the ESP32 is the hardware-based firewall to protect your companies WiFi against intrusion.
