Getting all style definitions on my server

Good day community,

I want to get all the style definitions on my server. Then assign permissions to these dynamically using a service. I know how to assign permissions dynamically however, I am unsure about how to get all the style definitions that are on my server. 

I saw the spotlights search on searchFunctions it could be helpful.

Has anyone tried something like this before?

Best Regards,

Janice
