Hi,
Yes I read that Hyperlink column formatting is limited to http, but that was a post in 2015 :)
Besides using a hyperlink column and always type in the phone number preceding with tel:xxxxxx , is there any JSON way to put the 'tel:' part in front of it?
i tried so many things but either the value disappears in the page of SP complains it is not correct JSON :)
thanks!
