Touch screen wake up from deep sleep

[gopro2027]

Wanted to start a thread here and ask if anyone is able to wake up from deep sleep from a touch on the screen?
Something like touchSleepWakeUpEnable but for screen input.
I attempted to use

touchSleepWakeUpEnable(GT911_TOUCH_CONFIG_INT_GPIO_NUM, THRESHOLD);

and it said

[ 30001][E][esp32-hal-touch.c:273] touchSleepWakeUpEnable():  No touch pad on selected pin!

which makes sense I guess...
Is there any way to do this with a screen touch?

My goal here, btw, it to put it into low power mode if it is idle for use on battery power.
If deep sleep is not an option, is there a shutdown command? I know there is a reboot in esp32 but what should i use when on battery power to turn off if touch to wake is not an option.

Hi Gopro,

I looked at https://randomnerdtutorials.com/esp32-deep-sleep-arduino-ide-wake-up-sources/

External Wake Up (ext0)
There is a function esp_sleep_enable_ext0_wakeup(GPIO_NUM_X, level)
Using the INT from the touch might work!?

Also, turn off the screen backlight and the display controller!
