ViewModelProvider not taking "this" (MainActivity) as its owner in kotlin Android Studios - android-studio

Question

I am trying to communicate between MainActivity.kt and sharedviewmodel.kt which is of type viewModel() for WearOS, But when i try to create an instance of the sharedviewmodel.kt in MainActivity.kt by below lines
private lateinit var viewModel: sharedviewmodel
viewModel = ViewModelProvider(this).get(sharedviewmodel::class.java)
when i pass "this" as owner of the ViewModelProvider, i face a error called
Required : ViewModelStoreOwner
Found : MainActivity
Kindly someone help to solve the issue,
Find the MainActivity.kt and sharedviewmodel.kt below.
import android.app.Activity
import android.os.Bundle
import android.util.Log
import androidx.lifecycle.Observer
import androidx.lifecycle.ViewModelProvider
import com.example.watch7_view_model_example.databinding.ActivityMainBinding
class MainActivity : Activity() {
private lateinit var binding: ActivityMainBinding
private lateinit var viewModel: sharedviewmodel
var tag = "view_model"
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
binding = ActivityMainBinding.inflate(layoutInflater)
setContentView(binding.root)
viewModel = ViewModelProvider(this).get(sharedviewmodel::class.java)
viewModel.azimuth().observe(this, Observer {
Log.d(tag,"data")
})
}
}
sharedviewmodel.kt
package com.example.watch7_view_model_example
import androidx.lifecycle.LiveData
import androidx.lifecycle.MutableLiveData
import androidx.lifecycle.ViewModel
class sharedviewmodel:ViewModel() {
private val azimuth: MutableLiveData<String> = MutableLiveData()
private val elevation: MutableLiveData<String> = MutableLiveData()
fun azimuth(): LiveData<String> = azimuth
fun elevation(): LiveData<String> = elevation
fun azimuth(azimuth_t: String) {
azimuth.value = azimuth_t
}
fun elevation(elevation_t: String) {
elevation.value = elevation_t
}
init {
// Setting default value
azimuth.value = "0"
elevation.value = "0"
}
