Help request icon (question mark in callout)

[giovannimalausa]

Describe the requested icon(s)

Question mark inside a callout, meaning "Help request", "support request", "support chat", possibly "Request help".

At the moment, there a few alternatives including the question mark in a circle, a simple question mark and a lifebuoy.
The lifebuoy might be unclear for some, the other icons are suited for "support" or "help", but they lack the interaction part (support request, support chat...).

Current results for "help":

I'd go for a simple callout with a question mark inside, similar to this (found on the web).

It would be great to also have variations, like we currently have with icons (possibly also the orientation of the callout "point").
