Unable to connect to the Zellij session on MacOS hosts

MacOS doesn't have support for XDG_*. Therefor `zmate` can't find the Zellij session of the host, making it impossible to connect to MacOS hosts.

Has anyone of you worked out how to reliably lookup the Zellij sessions on MacOS? On Linux, `zmate` can just  pass down `XDG_RUNTIME_DIR`  via env-var. But it has been reported to me that this is not sufficient for MacOS.
