How to do Signature Capture in Expo?

I’m trying to understand how I can do a signature capture in Expo. Something similar to this.`.

I have been able to find some directions on this post but it seem to be outdated with versions.

So anyone has any idea on how I can implement this? I guess pixi.js would be the right solution but still no idea where to start. Thanks in advance!

Maybe start with one of these examples?
