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;                                                                                                  

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              
/usr/bin/chromium-browser \
--enable-accelerated-2d-canvas \
--enable-hardware-overlays \
--enable-gpu-rasterization \
--enable-direct-composition-layers \
--noerrdialogs \
--disable-infobars \
--kiosk \ \ \ \ \ \ &


while true; do
	sleep 10

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?
