You cannot open the application because this application is not supported by this Mac, Big Sur Silicon mac

I am using current latest Electron Beta build to create dmg at Big Sur Silicon mac. Build has successfully created and installed. Once i try to open app i see below error.

Once I run build through electron command then app is working fine but after dmg create app is not working.
Anyone has experience this issue?
