Simple shared view that contains a Mirror column value

This seems like such a simple requirement, but I cannot figure it out, and can find nothing in the forum history either.

I have a Board of Tasks, where each task gets Assigned a user from a User Board. The column that stores the assigned user is a Mirror column, so the assigner can pick from a common list.

What I want to then do is get the Tasks Board “Shareable link” from “Share settings” each day, send that link to all of my users, and have them see a READ ONLY list of tasks and assigned users. But they only see the Tasks Board info and NOT also the assigned users.

What do I need to do to give my team a complete view of each task i.e. all task details and the assigned user?
