How and where are your pinned tabs stored?

[JudahFree]

I've been using Zen Browser for about a day now to replace both Firefox and Arc for my day to day (Doing great so far by the way!). I want to use it on my Win10 and MacOS machines but currently, the sync feature doesn't bring over your pinned tabs (It does bring over my workspaces and color choices though which is handy).

I wanted to know how Zen Browser remembers what tabs you've pinned for each workspace and where it stores that information. I want to copy the files holding that information and dunk it into the installs on my other machines, not the best solution long term but I'd rather not spend more time re-finding and re-pinning everything twice.
