Guys - is there a list of Go functions that are included in the body transform middleware. I see a limited set working (range, if, etc) but if I try some of the inbuilt functions detailed here Introduction to Hugo Templating | Hugo such as delimit, split etc the Test in the dashboard returns function not defined.
The docs also mentioned Sprig functions being included but it is not clear how to call them either without getting a function not defined response.
