customAttributes doesn't work?

[losh11]

In my Chatwoot inbox I've setup a customAttribute called nexusversion, and it's being passed into the widget like this:

const customAttributes = {
    nexusversion: '1.0.4',
};

However inside of the dashboard, the nexusversion attribute doesn't seem to be filled in. I'm running the latest version of Chatwoot through docker on a self-hosted system.
