Flex: When text too long break into new line

I was thinking if it is possible to achieve following using css flexbox.

In the layout, there are originaly 2 div next to each other. Left one contains group of icons and has a fixed width. Right one contains text, which can be potentially quite long.

Is there a way, how to make using only css (especially flexbox), that when the text is too long, the div will break onto the new line (under first div)?
