How to run one-time script right after fab plugin installed?

My plugin is a third-party plugin which includes some binary (like shared library on macOS and Linux). These files need to be installed with execute permission so that my plugin can work correctly (because they need to be loaded into the editor).

The current Fab plugin publish and distribution workflow is as follow:

  1. The developers build and export (pack) their plugin into zip bundle (here Zip file will strip the file permissions)
  2. The developer submits the plugin zip bundle to the Fab for reviewing
  3. The Fab reviewing team will build and pack the build artifact (I don’t know what file format it is, but here it really striped the file permissions)
  4. The end users install the plugin from fab with Epic Game Launcher (download the artifact bundle and extract to the engine plugin folder (here the permission will miss again)

After the user installed the plugin on their end, the plugin cannot work because of lacking the correct permission. Obviously with current workflow, Fab platform is not really ready to distribute Thirdpary Plugins on macOS and Linux systems.

I just wonder is there any approach to do some scripts work during the plugin installation process or just right after the plugin installation, just run a one-time script to config the plugin file permissions?
