Where is intensity for bloom shader?

I am using Urp’s shader for bloom in my own render pass, but I can’t seem to locate the intensity value.
Threshold, clamp, and all the other values are within _Params, but not intensity.
To clarify, I am talking about an intensity value that will yield similar results to the intensity value in the built-in volume component’s bloom setting.

This is a Bump.

This is another bump.
