Chromium, RPi, and Longlived tokens

So I have two raspberry pi sbc’s running chromium in kiosk mode hooked to monitors:

#!/usr/bin/env bash

xset s noblank                                                                                                    
xset s off                                                                                                        
xset -dpms

function cycle_refresh_pages()
{
	while true; do                                     
		  sleep 30                                                                   
	      xdotool keydown ctrl+r; xdotool keyup ctrl+r;                                                     
	      xdotool keydown ctrl+Tab; xdotool keyup ctrl+Tab;                                                                                                  
	done	
}

unclutter -idle 0.5 -root &                                                                                       
                                                                                                                  
sed -i 's/"exited_cleanly":false/"exited_cleanly":true/' /home/pi/.config/chromium/Default/Preferences            
sed -i 's/"exit_type":"Crashed"/"exit_type":"Normal"/' /home/pi/.config/chromium/Default/Preferences

while true; do
	sleep 10
done

Even if I log on and “remember me” the auth will eventually be lost. There’s trusted network login, but I understand that is deprecated. Is there any way to pass chromium a long lived token on startup in a way that is valid?
