Publishing iOS app created in Animate

I am not what you would consider an app developer, but a few years back using Adobe Animate a lot of YouTube tutorials, google searches and this community I managed to develop an iOS based on the UK driving test. To date I have reached over 12000 downloads 99% from the UK market and featured in the 'Learn to drive the easy way" story on the app store.  Small change I know! but for a one man band with no experience or advertising I’m happy.

I have recently wanted to update the app and publish a second to support the first one. I am really struggling to get anywhere when publishing. Is it even possible to do anymore? I’m feeling very overwhelmed and any advise would be appreciated. (Even if the advise is for me to give up haha)

I have downloaded the new Harman Air SDK but my Mac wont even let me debug on desktop
