Sparkle ring animation

My goal is to create Apples activity ring sparkle effect. So I found Paul Hudson's Vortex library. There is already a spark effect, but I don't know how to create a custom one that fits my needs. I'm still quite new to SwiftUI animations. Does someone have an idea how to do it?

 VortexView(createSparkle()) {
                Circle()
                    .fill(.white)
                    .frame(width: 16)
                    .tag("circle")
            }

 func createSparkle() -> VortexSystem {
        let system = VortexSystem(tags: ["circle"])
        system.birthRate = 150
        system.emissionDuration = 0.2
        system.idleDuration = 0.5
        system.lifespan = 1.5
        system.speed = 1.5
        system.speedVariation = 0.2
        system.angle = .degrees(330)
        system.angleRange = .degrees(30)
        system.acceleration = [0, 3]
        system.dampingFactor = 4
        system.colors = .ramp(.white, .yellow, .yellow.opacity(0))
        system.size = 0.1
        system.sizeVariation = 0.1
        system.stretchFactor = 8
        return system
    }
