How can I grant access to the Felix Console to additional non-admin users?

The Apache Sling Web Console Security Provider OSGI component takes care of authenticating Web Console users against the JCR repository.

Its exposed configuration allows entering AEM users and/or groups who will be allowed to access the Felix Console.

Read-only access is currently not possible.
