It is in osiris.
When you are in osiris, just type the word you are searching, and ctrl space will sort you all apis related to this word.
Totally forgot about that. Thanks.
You can also look at the
full list of Osiris APIs, which gets generated after you used "generate definitions" for the first time in the story editor.
I'm aware of that list, but the last time I tried a few out, the editor didn't recognize them. ContainerIdentifyAll, for example.
