Markdown-style bold and italic in Calc

I just noticed that in calc, If I write the following in a cell:

test *demo* 123

The result will format as:

test demo 123

Is there a way to have a substring formatted as Italic in a similar way?

I tried with test **demo** 123 but it doesn’t work.

For italics, use a slash (/), so:

test /demo/ 123

That works, thanks!
