Thank you for the update. I tried looking up a manual or API documentation for the custom behaviors feature but couldn't find any. Could you please share a link if it exists?
If not, please let me know where I can find "Create new behavior" button and I'll fiddle with the feature until a documentation is available.
Thanks

In general, behavior documentation can be accessed by clicking the "Help" button in their settings panel. You can add a custom behavior by selecting it from the "Logic & Math" section in the behavior editor (added at the bottom).
The behavior docs are sparse for this one, since it doesn't have any logic by default. Once you add the behavior and open its code editor, there is a "How Does This Work" button at the top, which has a short getting started guide. The code editor itself also has several templates to start from.
I'll be adding a Custom Behaviors section to the behaviors documentation on the site as well, but that's not live yet.
