Qt online installer should ship all licenses in separate plaitext files

In Qt Online installer directory Qt/Licenses we get:

ThirdPartySoftware_Listing.txt
LICENSE
LICENSE.FDL

But non of these license files mentions, for example, ICU license, while libicu* are shipped and we have to bundle them with our application too.

One can find ICU licenses "buried" in docs within Qt/Docs/Qt-5.13.2/qtwebengine/qtwebengine-3rdparty-icu.html, but that's unusable for distribution.

It would be convenient if Licenses directory contained plaintext files for all third party licenses, available to copy during CMake/QMake run, for example, to the output directory, ready to build installer, etc.

While currently Qt user have to manually sync relevant license files from upstream.
