Personally, the authors I've worked with use Content Warning as the term. For example, the opening of Law and Order SVU pretty clearly spells out you're in for some deeply disturbing shit.
Trigger warnings are content warnings, just spelling out what the content is: i.e. suicide, cutting, rape, etc.
To use one of my stories that's on a podcast:
> This is an adult story for mature listeners, if that's not your cup of tea or there are children listening, you can skip this story and come back next week. Content warning: this story contains mentions of past self-harm and past traumas.
Maybe that's a little specific, but it gives you an idea of how graphic the content is. Regardless, I personally know some of the people listening who will want to skip my story.
> I was under the impression that trigger warnings were something different
So, the basic intent, on the face of it, is a little different (a "trigger warning", properly, warns of something which may trigger PTSD, a content warning merely warns of something without any particular view on _why_ someone might want to avoid it), but in practice they're functionally similar.
