Informative / Confirmation popup with command and Projection action

Hello everyone
I’m looking for the packages / procedures to use to generate an informative and / or a confirmation popup, but can’t find it.
For error, we use “Error_Sys.Appl_General” procedure which trigger an error modale/pop-up on the cloud client, but for user experience, I’d like to use different kind of popup corresponding to the result of the action.

Thank you
