New to github need help ASAP

So I’m my companies Cyber-security analyst. We are obviously using github as the depository. Is there anyway for me to convert the zip file of the app into an IPA and APK file? I need to run some tests on it. Since the company’s a startup the most up-to-date version of the app isn’t available on the appstore nor googleplay store. However, inorder to test the app with a dynamic and static analysis I need the APK and IPA file. I’ve tried looking this up nothing I have found is coming up. The coders don’t really understand what I need from them that is why I am asking you guys here since they just gave me access to the git thinking it will help me get the items I need. I do think that is true but I’m not sure how to convert it. If this isn’t the correct way to get IPA and APK files to run tests on can someone please help me! I can’t find anything on the internet. I was invited to testflight and firebase but I can’t figure out how to get the files from them onto my computer. So they decided to try to add me to git and see if that would help.

how about this one

Didn’t mean to double post. Wasn’t sure if this was going to get approved. It worked to convert the zip to APK. Need to also convert the zip to IPA. that zip only converts to APK and a few others not IPA. UHHHH.

That tool Didn’t convert it correctly so wasn’t able to get an accurate report. Need it to be converted to a x86(32-bit or 64bit) in order to dynamically test the app’s security.
