Get generic value from a generic struct using reflection

Imagine I have the following struct:

type MyGeneric[T string | int] struct {
}

I want to check whether the generic used to instantiate that struct was a string or a int when creating a new MyGeneric.

myGenericString := MyGeneric[string]{}
myGenericString.canHandle("hello") -> should return true
myGenericString.canHandle(8) -> should return false

func (mG MyGeneric[T]) canHandle(value any) bool {
    // how to get what T is the same type as value
}
