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 https://www.elastic.co/guide/en/kibana/7.2/plugin-development.html.

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.
Andreas
