How to add Rich text (bold, italics) in push notification

Does anyone know how a JSON payload should look to show bold or underline text within a push notification message? I can do line breaks with "\n" - anything equivalent for bold or underline?

As it is now you can't show bold text within the push notification message body.

However the title is bolded if you set that text.

Thats what I thought. But was hoping iOS10 would have rich text push notification capabilities.
