Install the specified version qgc on arm64 ubuntu

The most convenient and almost only way to use QGC on arm64 is to download and install it using flathub. But flathub’s QGC only has specific versions, such as the current version 4.3. But for many px4 developers, specific px4 versions require specific QGC versions for testing. Can anyone provide more versions of QGC to flathub? I don’t know who provides the software currently on flathub, so I can only ask for help here.
