External sync on the arducam sensor?

1.Which seller did you purchase the product(s) from?

2.The Model number of the product(s) you have purchased?
B0240
3.Which Platform are you using the product(s) on?
Raspberry Pi Zero W
4.Which instruction are you following?
https://www.raspberrypi.org/forums/viewtopic.php?t=281913
5.Has your product ever worked properly?

6.What problems are you experiencing?
I read about the rpi HQ camera modules having external trigger IO on them here: https://www.raspberrypi.org/forums/viewtopic.php?t=281913 which mentions that you can wire the cameras XVS points together and have them trigger each other when a photo is taken. Is this something that is also possible on Arducam cameras? I have 4 pi zero W’s and was considering buying 4 IMX477 sensors to take synchronized photos between all of them

Might be a moon shot but if anyone has a guide on how to go about doing that, that would be extraordinarily helpful as well.
7.What attempts at troubleshooting have you already made?

8.How would you like us to help you?

Also, would I be able to use the two cameras on a stereo hat as masters, and two other cameras on separate Pi’s as the slaves?
