How to set content Bold in List items

I wondered if it is possible to make the content of a list item bold.
I tried using this:
‘Hello, World!’.bold() and then display the string, but what is displayed is as follows:
Hello, World!
Is there any other way I can go this?

It is not currently possible to format the text inside of a List Item.

You can apply that kind of formatting to text inside of an Object Table, or by using custom HTML.
