• My pull request is made against the dev branch.
• I have ensured that the changed library can be built on your target system. I did not introduce any platform-specific code.
• I have ensured that all methods and functions are fully documented using doxygen style comments.
• I tested my commits, by adding a test case to the unit tests if needed
• I have ensured that I did not break any existing API calls.
• My code follows the coding style guide (if you are not sure, match the code style of existing files including indent style etc).
• I have not built my pull request using AI, a static analysis tool or similar without any human oversight. Where I have generated this pull request using a tool, I have justified why this is needed.

not sure if we want this feature at all. It's currently in beta. I wonder why this feature is even documented, but hey it's discord...
Also:

The available selection of avatar decorations will change periodically, and can be used by Nitro Subscribers for a limited time only.

I think no one is seriously using this in their bots. At least not yet
