Show custom app for kibana_read_only Users

Hi, we are developing an Kibana Plugin which exports an Custom App, as described in the official guide

We are wondering whether its possible to enable that app for kibana_read_only Users, so that they only see the dashboards + the custom app in the main menu on the left side.

If not available yet, could you give tips for starting a contribution in that direction. I’m thinking about the “security tenant” selection app that is also visible to read_only users, how does it work for that app? Any pointer to the code in github would be appreciated.

Thanks in advance.
