Feature Request: After installing a package, provide a shortcut button to show the app from the confirmation in-app notification

• My proposal does not exist in the PLANNED & NOT PLANNED.md document
• I have not found any other opened issues on the same feature request
• I believe this fits within Warehouse's scope of Flatpak management

Describe the feature idea in detail

When you install something from the "Install Packages" page, upon completing the installation it shows an in-app notification for 2 seconds or so, but it disappears quickly and does not provide an action.

I often find myself wanting to see the details of the installed app after installation (I rarely install more than one app after another), but to do so I have to manually go into the "Packages" page and search for it.

I think it could be nice if the in-app notification lasted a bit longer and provided a "View app" (or "Show", or whatever) button that, when clicked, would take me to the "Packages" page with the app already pre-selected (and scrolled to) in the list. From there I can view its details, or click the "Open" button.
