Is it possible to do code signing after releasing an electron application?


I am relying on Squirrel to update my application. The update is working without a problem.
The application does not have any code signature, and I am trying to get one. My question is, is it possible to code-sign an electron application that has been updated without a code signature in the first place? I am planning to code-sign it and publish it through a regular update.


Just so you know, the application only targets Windows.
