Create a request with API, how to add a hyperlink into the description field?

Hello

I am creating a request with powershell with API.
I'd like to insert a hyperlink into the description field. What is the syntax I have to use, so I'm able to click on the hyperlink?
I already tried with html syntax like $link = "<a href='http://www.metas.ch'>Test</a>", but only the word Test is shown without a clickable hyperlink.

Regards,
Markus
