Question about 2.3.2 (GraphQL)

Release notes said this:

• Updated Monaco Editor with GraphQL support for syntax highlighting and mode

What does this mean exactly? That the monaco editor simply visually now correctly shows colors/spacing etc with graphQL code?

Because my actual question is about how to run a GraphQL query within Wappler. Is this at all possible in the regular serverside API action step? if so, how do I do this exactly? Or do I actually need to go to /dmxConnect/Api/file.php and put the GraphQL code in there manually?
