CEP-Resources VS open-type-features

I downloaded the version from github (this one - https://github.com/Adobe-CEP/CEP-Resources/tree/master/ExtendScript-Toolkit ) but it tells me that the developer needs to update the software for me to install it. Can anyone help please? There's a ton of help for After Effects scripts but I'm struggling to find much support for PP. Thank you!

A good point to start is here: https://github.com/Adobe-CEP/Getting-Started-guides https://github.com/Adobe-CEP/CEP-Resources https://github.com/Adobe-CEP/Samples https://github.com/Adobe-CEP/Samples/tree/master/PProPanel https://ppro-scripting.docsforadobe.dev/ Great examples to learn from. Basically, Adobe extensions are a website UI (html, javascript, nodejs support) that talks to ExtendScript (old version of javascript), which is used to invoke commands for Adobe software. Know that Adobe is currently in a transition period, where they switch from CEP (Common Extensibility Platform, structure I described you above) to UXP (Unified Extensibility Platform). UXP will merge website and ExtendScript commands in one context. I guess it will happen in 1-2 years, but CEP is promised to be supported for longer.

Handy Hands is written using the CEP framework: https://www.adobe.io/apis/creativecloud/cep.html. You can use web technologies (html, css, js) for making the panel and buttons, but you'll still have a jsx file as well for executing the code that interacts with the other parts of AE (things like adding layers).

Hello! I tried to follow these guidelines — https://github.com/Adobe-CEP/Getting-Started-guides — to build an extension for Adobe InDesign 2021 (macOS Big Sur). I was able to make my panel (EvoDesigner) show up but no contents appear in it. I also tried to install a sample extension — https://github.com/Adobe-CEP/CEP-Resources/tree/master/CEP_9.x/Samples/CEP_HTML_Test_Extension-9.0 (also tried it with CEP_10) — but it happens to have the same problem. Any thoughts on how to solve this problem?
