Blank "asking for password" screen on macOS for install with no explanation

[cdrage]

We added the macadam.js library to bootc extension.

The problem is that on startup of the extension, we get a blank screen asking for a password, which is related to macadam.js running this piece of code: https://github.com/crc-org/macadam.js/blob/main/src/index.ts#L127

This does not show any explanation to install it. We also cannot control how it's used since it's part of the init script, so it'll run every time. https://github.com/crc-org/macadam.js/blob/main/src/index.ts#L98

I believe we should instead show an interactive "Install" / "Cancel" dialog that pops up, similar to other actions within Podman Desktop that require privileges. Or else users are just entering their password having no clue what it's doing.
