VFX graph emitter/system time?

Hey everyone,
I have been working with VFX graph for a little bit and got most of the basics down…
However right now I am stuck on something that seems very basic but nothing I have tried worked.
I want my spawn rate to escalate as the system lives. it seems like such a basic ask and I can do it very easily with the old particle system but nothing I have done works with VFX graph.
The only node I found that comes close to be able to drive what I want is VFX total time however that is reset when the whole object is enabled not from when the spawn of the system actually starts.

Any help would be appreciated.
