Authenticate users in messaging widget when they are logged into the Help Center

Please give a quick overview of your product feature request or feedback and note who in your org is affected by this issue 

When we soon add the messaging widget to our application and to the help center, I need end users who are already authenticated in the help center to also be authenticated in the web widget in the Help Center. As it is today, a user who is already logged into their end user account in the help center is not authenticated in the messaging widget in the help center, so they can't see their past conversations or any of the other benefits of being logged in. 

What problem do you see this solving? 

Without this, I can't show the messaging widget to customers on the help center. Them not automatically being authenticated in the messaging widget when they are already logged into the Help Center seems like the most basic thing that needs to be supported by Zendesk. As it stands today, it would be such a horrible and confusing user experience that I am forced to not show the messaging widget on the Help Center.

When was the last time you were affected by this lack of functionality, or specific tool? What happened? How often does this problem occur and how does this impact your business? 

Zendesk is starting to really roll out messaging and I imagine we are getting close to being forced to move to messaging. As we've been working through the configuration and technical implementation, we realized it isn't even authenticating/recognizing users who are already logged into the Help Center. 

Are you currently using a workaround to solve this problem? (If yes, please explain) (1-2 sentences)

We just aren't going to show the messaging widget in the Help Center. We'll have it in our app, but I want it in both for a cohesive and consistent user experience, but that isn't possible.

What would be your ideal solution to this problem? How would it work or function? 

It's simple. If I log into the Help Center and then launch the messaging widget there, I should be authenticated in the messaging widget.
