Where is sensitivity slider for 3D Touch on iPhone 13pro?

I am a call of duty mobile gamer and previously use the iPhone XS max with 3D Touch assist. I was able to adjust the sensitivity of this 3D Touch in my settings, but can no longer find the slider. All that I can find are the options for fast or slow. Anyone know a workaround or solution to restore the slider for specific 3-D touch assist settings?
