Sadly, the screenshot looks obviously artificial to me. Like handwriting fonts, I'd be very surprised if anybody thought it was really handwritten.
It's not open source (because it is my handwriting (because my progressive MS means I can't do it manually)), but here's my hack: https://imgur.com/a/frqG0cu
As sjv says above, there are still plenty of tells in mine. So I think this module is very unconvincing.
Maybe I've spent too much time being finicky or am just being braggy (definitely not beyond me, sorry), but 'realistic'?
