### Describe the improvement

When installing or automatically updating and the unigetui elevator requests admin priviliges to update a specific program then with this improvement the elevator would tell the user which program is requiring admin priviliges.

Currently the elevator looks like this:

And if you click "Show more details" it looks like this:

Potential solution is that the unigetui elevator renames itself for every admin priviliges request so that instead of the big letters being "UnigetUI Elevator" then it would say something like "UnigetUI install Firefox" or "UnigetUI update Firefox" (Firefox is the example here). Though it would be even better if there could just be a small text description that shows what action UnigetUI wants to take (update or install or other) and on what package.

### Describe how this improvement could help users

From my point of view, it would increase clarity and transparency over what UnigetUI is doing.
It feels a little strange every time to click yes to the unigetUI elevator when it is updating programs in the background just because I can't see what program it is.
And if I click no, because I want to see the program then I have to update it manually which somewhat defeats the purpose but is not a a big deal since I usually click yes.

Start by locating the UniGetUI elevator request flow used during installs and automatic updates, then trace where the requested action and package information are available. Done means the administrator prompt clearly identifies whether UniGetUI is installing or updating and names the affected package.
