Which version of Studio do you use? If 20.4.x, can you try to turn on ShowStudioX at Filter of Activities panel?
Or can you upgrade UiAutomation.Activites package to higher version?
In UiAutomation 20.4.3, as UseApplciation/Browser is categorized in StudioX, recent Studio cannot use it. So, as I mentioned in the above post, can you try to upgrade UiAutomation package to higher version such as bundled version of Studio 21.10.5 or the latest stable etc?
