First, it seems that ~/.config/lxsession/LXDE-pi/autostart does not exist by default.

1. copy the autostart

cp /etc/xdg/lxsession/LXDE-pi/autostart ~/.config/lxsession/LXDE-pi/

2. open the autostart with nano

nano ~/.config/lxsession/LXDE-pi/autostart

3. Then edit the autostart

@lxpanel --profile LXDE-pi
@pcmanfm --desktop --profile LXDE-pi
#@xscreensaver -no-splash
point-rpi
@chromium-browser --start https://google.com/

if you want to autostart incongnito mode

@chromium-browser --incognito --start https://google.com/

^ + x exit and save

then sudo reboot to try on

the various other browser modes:

• Application Mode: @chromium-browser --app. The browser starts up without displaying any toolbars.

• Full-screen mode: @chromium-browser --start-fullscreen. The browser starts in app. mode but expanded to full-screen. You can press the F11 key to break out of full-screen mode.

• Kiosk mode: @chromium-browser --kiosk. The browser starts in full-screen mode but does not respond to the F11 key, nor to any command to get it to switch tasks.
