@helloanoop it should be almost okay (the build is currently running on PR only but I'll convert it once every thing is ok)

You'll need to define some env var on GitHub (probably here: https://github.com/usebruno/bruno/settings/secrets/actions) to properly sign macOS & Windows build: https://www.electron.build/code-signing

Once thing I can figure out is why the Windows build is totally failing with an unhelpful error ...

Ping @helloanoop @j0k3r, can we please merge this? This is for #541. Thanks!

Thank you for taking the time to create and submit this PR @j0k3r !

We have an internal process in place that generates a build, which then undergoes testing for a few days before being uploaded to GitHub releases.

Closing this PR, as it doesn't align with our current workflow.
