Custom shapes possible?

Hallo everyone,

on powerbi.tips there is an layout calle splash-o-red.

https://powerbi.tips/product/layouts-splash-o-red/

Seems like it has an custom arrow shape in it!

The properties say it isn't a picture..How is that possible?

Since the out of the box shapes (rectangle, oval, line, triangle and arrow) very limited, I was looking for a way to implement custom shapes, but so far couldn't find a solution..

Maybe someone has an idea?
