HPSM 9.32 Self Service tailoring question - where are the templates stored?

The people who set up our self service (who have now retired and moved on) have a series of templates specifically for the ess.do app. When the user logs in, they select "standard requests" and then from a qbe they select a specific request, and an interaction form is displayed, with prompts and other information filled in on the form.

 

I've been asked to modify the description portion of one of the templates updating the instructions in the detail widget.

 

I don't know where to go to make such a change.

 

I have searched the help information and been reading for hours and still haven't found the information, so I am hoping someone can give me a pointer to where the templates are, or what help information to see.

 

Thank you
