Cannot Open on Mac Big Sur

[MikeBarberry-Flatiron]

I get this message when I try to open the application:

“Postbird” cannot be opened because the developer cannot be verified.
macOS cannot verify that this app is free from malware.
Chrome downloaded this file today at 12:45 AM from www.electronjs.org.

I think it's a Gatekeeper issue, have you checked this page?

That's expected, because I don't have apple developer account
For now you can do right click on app and choose "Open"

Any updates on getting this application signed/notarized by Apple so it passes the Gatekeeper function? My organization does not allow users to bypass Gatekeeper for obvious reason :).

If you build it from source, may be it will pass the restriction
