Reddit PRAW bot posting with my main account and not the bot

Question

I'm able to post images using python PRAW but it's only posting from my user account and not the bot.

reddit = praw.Reddit(
        client_id=secret.client_id,
        client_secret=secret.client_secret,
        password=secret.password,
        user_agent="my user agent",
        username=secret.username,
    )
    print(reddit.user.me())

sub_title = sub_title
title = title
reddit.subreddit(sub_title).submit_image(title, image_path=pic)

This is the instance I created the password and username is my account's

I tried changing the username to the name of the bot but it failed authentication.
