Trying to write simple hello world to firebase database - firebase

Question

I'm trying to write to my firebase Realtime database but I cannot figure why I cant. I'm just starting to implement it but I cant figure out why my .setValue()in my onCreate is not working. I've brought in my google-servies doc and i've followed the code in the tutorial in android studio but still no luck. I also dont think its an error with dependences but it still could be for all i know. I'm not getting any errors so im really at a lost. Has anybody any suggestions. Here is the relevant code:
class CreateAPostFragment : Fragment() {
var post = PostModel()
val database = FirebaseDatabase.getInstance("HERE IS MY URL TO THE DATABASE")
val myRef = database.getReference("test")
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
myRef.setValue("Hello World")
println("added")
println(myRef)
}
