Add ability to open a trigger from an URL

I don’t what to trigger anything. I just need an action to open a step via a url for inspection. This already assumes that I have a browser session open, authenticated, etc.

Consider it as a help for the developer to quickly find a specific trigger in the mass of triggers.

I am using the graph to analyze the apps and quickly find the offending trigger, if there is one.
