Is the companion object value of the class different from the companion object value of the instance?

Question

I'm new to Kotlin and I'm learning.

I wonder if the value of companion object of class and value of companion object of created instance are separate.

I want to change the value of companion object in a list instance created with class Person using companion object.

Below is the example code.

fun main() {
    val personlist : List<Person> = listOf(Person(1), Person(2), Person(3))
    Person.name = "ABC" // Will the name of the personlist change?
    personlist.name = "ABC" // error
}

class Person(val num: Int) {
    companion object {
        var name: String = "TEST"
    }
}
