Testing activities in new UiPath.UIAutomation with modern design?

Hi

With the modern design target actions requires an “use app/use browser” application scope. When using this how do you go around testing different individual actions ? Right click and ‘test’ on a single action will fail because it needs to run in the app scope. If you have multiple actions in the app scope, you might not want to run all of them, just one.
How can one do that in an efficient and easy way?
