How do you enter command line arguments? (SOLVED)

[Lowen-Beehold]

This has been driving me crazy trying to figure it out .

on the front page it says "Use --preview-method auto to enable previews." so I spent ages online looking how/where I enter this command. found this post on reddit -
https://www.reddit.com/r/comfyui/comments/15jxydu/comfyui_command_line_arguments_informational/
that says to "cd into your comfy directory ; run python main.py -h" so I tried running main.py with python but the is still no option to enter this command. I feel like I'm either being a simpleton or missing a key piece of information but either way can someone please put me out of my misery because I have spent a couple of hours already looking for answers.

Command line arguments can be put in the bat files used to run comfyui like this separated by a space after each command
