Browser emulation for Discord in C# or python?

Question

Emulators

Greetings, is it possible to write such a program so that with it you can log into your Discord account with email and password? And you could do things like join servers. But the problem is that I don’t know how to enter data into the input fields on the site and do something like a cookie so that when I log into my account from this PC, the program can not only authorize, but also do something from the name of my account, that is, how to remember and save authorization. And when I make, for example, a request to an address like discord.gg/ABCDEF (invitation link to the server), then the account I logged into was attached to the server. I would be happy with hints where to dig or examples, it is possible in C # / Python languages, I searched in Google, but there is some vague information that is still incomprehensible to me
