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.

Hopefully, you already found an answer, though if not then you are looking for particle age node. You can multiply it by whatever number you want or curve and attach to the spawn rate.
