Markdown for callout?

I’d like to be able to just use inline markdown to format a block as a callout (actually, I’d really like a “Quote” formatted block, but I think Callout is the closest). For the most part, markdown works as I type, but my trivial attempts using quasi-standard markdown

==testing==
:bulb: some text here

and what I’d usually use, >, parses as a toggle instead of a quote block

this is a test

Do you guys have any docs about what custom inline parsers you’re using for things like this?

Thanks,
