I had to make booleans not be required so I didn't have to map Salesforce's "Unread By Owner" field. But syncing properly mapped the boolean!

I had some troubles to configure the whole thing, but when that was done, it works 👍

@mqueme Thank you for this. I was just coming to put in the same issue as I've manually made the changes locally and was looking to see if I should make a pull request.

I've tested the staging branch and it works well.
