How to put a warning inside code

I’m trying to write my own action in javascript and a bit ago I saw an action create a warning in the source code which I would also like to do but after looking around a bit I couldn’t find anything telling me how to do it.

(example of what I mean)

Thanks in advance!

I believe those are referred to as “annotations”

Thanks after googling around a bit I found some things that got me on my way

Great, glad I could help :slightly_smiling_face:
