Native Linux Codex App - Am I allowed to post it on GitHub?

I am curious to know whether or not I can post a native Linux client for the Codex App on a public repository? I don’t see any license information with the provided app.asar package shipped with the Codex App or anything on the website, so I am under the impression it would be ok, but I am not here to cause problems, but fix them.
