Help understanding how to get a custome script from AWS for auto translation

Hi, I use and Adobe software called Robohelp to create technical content. In Robohelp there is a translation function, where I can set language sets to translate the English source content into a chosen language.

I can handle translations manually, which means I export xliff files to my translator and then re-import the translated language xliff back into the Robohelp software.

There is also an automatic function and Robohelp has a few translation service profiles already pre installed, which I have been able to prove the process works by connecting to Google, which does work fine.

I'd like to connect to AWS translation and I need to understand what I need to do, as it's not clear to me if I'm honest. Robohelp needs a custom script from AWS, which has my details I beleive, as this is what I had to do to get Google translate up and running.

Can anyone advise as to how I get the custom script out of the AWS system?

Once I have the script, I then point the tool to the script location and it should work. I have my APi key, but I could also just need help confirming if the end point is (https://translate.eu-west-2.amazonaws.com)
