The EFB Challenging Weather Finder app has been released and is available exclusively on the MSFS2024 Marketplace.
You can find it under the Customization category, type Tool, or simply search for it by name.
Note: The MSFS2024 Marketplace currently does not offer a Free Trial option for this type of add‑on.
P.S. Here you can find a quick demonstration video.
