( API) App to download all my signed documents

"I created a simple Python app to download all my signed documents and audit reports from Adobe Acrobat Sign.

However, I’m unable to proceed with obtaining the API key.

It seems that my Basic plan doesn't provide access to this feature.

Is there any solution for how I can move forward?

If you'd like to review the code, it's attached in a .TXT file.

In the attached image, you can see the restriction preventing my Basic account from accessing the API."
