How to make it wrapping lines at the edge of view?

I have a simple markdown string like below,
let markdownString = """

淡泊明志，诗书传家——文徵明《绝句》赏析

    这首题为《绝句》的诗作，是明代著名书画大家文徵明的一首佳作。此诗以简练的语言、生动的意象和深邃的意境，展现了诗人独特的人生态度与价值追求。

"""
Markdown(markdownString)
This shows the result like this

it doesn't wrapping the lines at the edge of the view, instead it provides the scrollbar for horizontal scrolling.
Have tried fixedSize, multilineAlignment, etc, but none of my trial works.

Anyone has experience on this?
Thanks
