ServiceOperationManifest documentation for custom connector extensions

[bgelens]

I'm building a custom connector extension for internal use and I'm having a hard time il-spying the ServiceOperationManifest possibilities. For example, I require an input which generates a drop down (like the Enum but without the option to provide a custom input) and dependent on the selection, an additional required parameter is surfaced or not (similar to ConstraintDependentParameter in ConnectionString parameters).

My example is just one of the things I need. It would be nice to find some documentation but so far I've stranded.

Is there any public documentation available on what we can do here?

Yeah, getting this to work would be impossible without decompiling existing connectors, which is a real PITA.
