Kotlin error: 'LocationRequest.create()' not working despite updating LocationRequest.Builder

Question

It asks me to update LocationRequest.Builder, but I change it and I still get an error enter image description here

I tried the LocationRequest.Builder method, but it keeps getting an error

val locationRequest= LocationRequest.create().apply{
            interval =0
            fastestInterval=0
            priority = Priority.PRIORITY_HIGH_ACCURACY
            smallestDisplacement = if ()
        }

Which code would I replace it with, it's for andriod studio kotlin
