Initial state for a particle

Phaser 3
1

I wanna make my particle to be created with some initial state like alpha = 0, scale = 0.
so that the particle will be then fade-in, and then fade-out?

   use start and end -

alpha: {start:0.0,end:1.0},
scale: { start: 0.0, end: 1.0 }

sorry, but what I need is:
from alpha 0 born -> to alpha 1 -> then to alpha 0 die
