I searched all over the place for any kind of details or instructions on how to get astrobox gateway working with a touchscreen. If anyone else is interested, follow the instructions in this link https://pimylifeup.com/raspberry-pi-kiosk/ and replace this in the kiosk script
/usr/bin/chromium-browser --noerrdialogs --disable-infobars --kiosk htps://pimylifeup.com htps://www.adafruit.com &
/usr/bin/chromium-browser --noerrdialogs --disable-infobars --kiosk http://127.0.0.1 &
Seems to work fine except an error message that pops up right before the kiosk loads. It doesnt appear to affect anything that i can tell. If anyone knows of a better way of doing this i would appreciate any input or instruction.
