Add extra files to .deb package

[JezerM]

• Electron-Builder Version: 22.11.7

• Node Version: 14.17.2

• Electron Version: 13.1.8
• Electron Type (current, beta, nightly): current

• Target: linux .deb

Is there any way to add files to a .deb or similar packages? For example, an app depends on external files located in paths like /usr/ or /etc/ and there sould be a way to add those files, the extraFiles config seems to approach this, but it only works in the build process.

When the .deb is built, those extraFiles are not included, therefore the installation through a .deb package would result in an unusable app as these files don't exist.
