Read-only access for group of users

Thank you for this plugin! I am trying to implement it for a small non-profit but have run into a stumbling block. Only the treasurer should be able to edit, and the “accountant” role does that. However, I need to give board members read-only access to everything. Granting the board eac_read_* access doesn’t seem to do anything at all. Granting eac_manage_report does allow them to look at the reports page, but nothing else. At a minimum, they need to be able to view accounts to see current balances, and should be able to display all income and expense items, but I can’t figure out a way to do it although it looks like it ought to be possible with all of the granular permissions that are available.
