Docs: Custom Hook Examples showcase TS and TSX but type: external only loads .js

[tegge]

What were you searching in the docs?

I was looking for the proper implementation of a custom Hook for "onSave" in example to check reachability of the domain entered in a field of the Configuration page.

Is this related to an existing documentation section?

https://splunk.github.io/addonfactory-ucc-generator/custom_ui_extensions/context/custom_hook_context/

How can we improve?

Please update https://splunk.github.io/addonfactory-ucc-generator/custom_ui_extensions/context/custom_hook_context/ to describe, how a tsx/ts csutom-hook would be loaded? The globalConfig example only loads .js files.

Got a suggestion in mind?

found the switch --build-custom-ui for the build command. Please update the docs.
