Librem 5 LibraryLoadException

From Briar matrix:

Hi! I am trying to run briar-desktop (java version) on a Librem 5 phone (Debian-based aarch64 GNU/Linux). I am getting an exception, where the relevant part seems to be:

Caused by: org.jetbrains.skiko.LibraryLoadException: Cannot find libskiko-linux-xrm64.so.sha256, proper native dependency missing.
