Need to run chromium browser on startup

I just installed linux 2019-09-26-raspbian-buster-lite for Raspberry Pi (headless)

 I need to to run chromium browser on startup. I have installed:

xserver-xorg xinit
chromium-browser
unclutter //to hide the cursor/pointer

I have created a file on my home directory called: ~/.xinitrc
with:

#!/bin/sh
xset -dpms
xset s off
xset s noblank

unclutter &
chromium-browser /path/to/your/file.html --window-size=1920,1080 --start-fullscreen --kiosk --incognito --noerrdialogs --disable-translate --no-first-run --fast --fast-start --disable-infobars --disable-features=TranslateUI --disk-cache-dir=/dev/null  --password-store=basic

I have added startx & to my rc.local

I cant get chromium to start on boot.
