Need to modify an already working Android App downloader script

I am using two scripts called OpenGapps and APKcrawler from here ([login to view URL]). Now these script download the Google Apps that are part of OpenGapps Gapps package. I need you to modify to include any other Android App that I may wish to download using these two or either of these scripts. Using these scripts as they are, I can easily download the default Google apps they support. There is a provision to download more aps, as one of the developers who is part of this project confirmed here ([login to view URL]). (Using the given sample text in a simple test file, I was abe to download Facebook and Instagram apps, easy. But not at their latest version, so we need to configure it, it seems) It looks simple, but I need it even simpler. I need you to create a custom script based on this, which allows my to input package name of Android apps I want to download using the script (the script scrapes many populer sources itself for the latest version of apps, so we don't need to look into that part) All we need is to how to make script looks for more apps, the apps we want to download. Thanks!
