I am facing a issue, just want to hide Query and Alert menu for a particular user group.I want just to show them only Dashboard and also want to set privilege on dashboard.Using opensource Redash 5.0. Please help in same.

Redash doesn’t support this use case because users with sufficient privileges to view a dashboard can also view the underlying queries (although they can’t make changes to those queries unless you specifically mean to allow it).

One alternative you could consider is to embed the dashboards into a separate page that does not require a Redash user account to view.
