How to set approval at after script section?

I have a job in which before script will do the installation of the product.
In the script section, we are running the product deployment command/functionallity.
At the after script section, we are running the cleaning up part of deployment.
Why I kept in after script? so that even the main script fails, the after script cleanup part will run.

Is there anyway to setup approval just before the after script section, so that until we can come here and click on continue, the cleanup won’t happen.

Please suggest.
