python-requests how to send cipher name/http2

I am trying to replicate the following client requests via python-requests.

Under client connection I see HTTP Version which is 2.0 and TLS version which is 1.3, as up to my knowledge I know that requests utilizes TLS 1.3. My requests are failing as of now.

And I wonder if I need to pass certificates. I would like to understand how this request is different from regular request which would be simply as

r = requests.get('someurl')

How can I use requests to use the exact client connection show in requests? I don't fully understand each pointer, How would I use h2 ALPN/ with that specific cipher name? I am not expecting an solid answer to the question rather an explanation would be much more helpful!
