Question about Gravity Sync compatibility

Hey, I was wondering if the whitelist functionality of this script would sync across different instances of pihole, since I have two piholes running for high availability, that are being synced with [Gravity Sync ](https://github.com/vmstan/gravity-sync). I runned the smart function of that syncing script after updating the whitelist of the main node, but no changes were detected (at least through the CLI). Any ideas?
Thanks
