I believe this can be done (clumsily) by setting up presets for different groups of apps, one preset per use case: https://genode.org/documentation/articles/sculpt-25-04#Custo...

Not ideal, but the Sculpt “desktop” is still immature. Genode is primarily a framework for building secure OSes, with Sculpt being a kind of demonstration piece to help devs understand how it works. It’s only recently that the project has had the resources to expand and grow Sculpt usability. I’m hoping they continue this work, as Sculpt has a lot of potential to be a usable and secure desktop OS. The backend is mostly ready, but it lacks UX investment.
