Design Studio / Lumira Designer - Planning Backend Messages

Hello everybody!

When using Analysis Office for Excel in a planning scenario, we regularly get pop ups for backend messages, informing the user of the status for certain actions. Like errors in planning sequences, numbers of selected data rows or refreshing/saving plan data.

I am having trouble on implementing similar status messages when planning in Design Studio / Lumira 2.X applications. Is there a standard funcationality to access those backend messages with scripting, or is this a case for SDK development?

Thanks in advance for anybody who can shed some light on this!
