Chromium kiosk mode: how to open multiple pages with the ability to switch between them?

Question

Chromium

Hello. I set up a kiosk on Debaian 9 - when the system starts, a special user automatically logs in and the $HOME/.config/openbox/autostart start script is executed:

chromium \
--no-first-run \
--disable \
--disable-translate \
--disable-infobars \
--disable-suggestions-service \
--disable-save-password-bubble \
--start-maximized \
--kiosk " www.google.com " &

Everything is cool, the user is in the system, chrome without buttons is open, it contains the desired page. But you need to open several pages at once with the ability to switch. How to do it?
