Niagara Mesh Emitter // Set opacity as curve over time

It’s all in the title, I need to be able to set the opacity over time of my Niagara emitter on mesh renderer.
If anyone has any insight that would be greatly appreciated.

PS : If I find a solution, I’ll post it here

You would commonly do this by animating the alpha channel of the ‘particle color’ in your Niagara system. This value would be read into the material assigned to your mesh particles (the node is again called ‘particle color’). There’s some good info on it here: Particle Expressions | Unreal Engine Documentation
