Chromium Multiple Tab and rotate

Hi All, I want to open 3 tabs on Chromium and rotate every X second, could you please give some directions.

Edit:
To add more tab

sudo nano /boot/dietpi.txt

Chromium

SOFTWARE_CHROMIUM_RES_X=1600
SOFTWARE_CHROMIUM_RES_Y=1200
SOFTWARE_CHROMIUM_AUTOSTART_URL=http://webpage1.com http://webpage2.com http://webpage3.com

But still looking an way to rotate tabs

Hi,

Many thanks for your request. Maybe you can have a look to following link
