How to write your own Telegram client in c#?

Question

API

Hello!
There was a task here: to write your own telegram client in c#.
I do not ask for any details on the code. The question is how to use the Telegram API.
There is such a dock, for example, the sendCode method: https://core.telegram.org/method/auth.sendCode
To be honest, I did not understand what was written there.
I understand that a request with parameters needs to be sent to the server that was indicated to me when creating api_id:

But how to do this? Through what method? POST, GET? Or is there something else altogether?
In general, I will be glad for any help, and if possible, it would be nice to see some examples with code.
Google issues only Bot API.
Thanks in advance.

I would recommend that you do not write your bikes, but use the ready-made library https://github.com/sochix/TLSharp
Well, or at least see how it is implemented in it
