I can confirm that just downloading the source from latest release and extracting the archive is enough to have it working on a linux/arm64 operating system.

Successfully tested on Oracle Linux 8.4 running on arm64.

It seems we just need to add arm64 as a valid platform on the install script checks, which is exactly what PR #198 does 👍

Fixed #206 and #198
