Rotate a spawned object whith onmousedrag and move it with onmousedown

Hello guys!!

I am a new unity programmer and i need some jelp. I am working to a project where i select a primitive mesh and spawn it to my scene. then sith a slider i can edit the spawned object scale and with another button i can change the object's color with random values. All good with that but i would like to be able to rotate the spawned object whith the onmousedrag and move it with the onmousedrop. Any ideas how can i manage something like that?

Thanks for your time here is my code so far:

using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.UI;

public class ChangeMeshFilter : MonoBehaviour { public Mesh[] myMesh= new Mesh[5]; private GameObject gObject; public Dropdown MeshSelector; private Slider scaleSlider; public float scaleMinValue; public float scaleMaxValue;

 void Start () 
 {        
     CreateObject();
     MeshSelector.onValueChanged.AddListener(SelectMesh);        
   
     scaleSlider = GameObject.Find("ScaleManager").GetComponent<Slider>();
     scaleSlider.maxValue = scaleMaxValue;
     scaleSlider.minValue = scaleMinValue;
     scaleSlider.onValueChanged.AddListener(ScaleSliderUdate);
 }
 void CreateObject() 
 {        
     gObject = new GameObject();
     gObject.AddComponent<MeshFilter>().mesh = myMesh[0] ;
     gObject.AddComponent<MeshRenderer>();
     gObject.GetComponent<MeshRenderer>().material.color = Color.green;        
 }
  
 private void SelectMesh(int index) 
 {     
     gObject.GetComponent<MeshFilter>().mesh = myMesh[index];
 }

 public void ColorChanger()
 {       
     gObject.GetComponent<MeshRenderer>().material.color = Random.ColorHSV();
 }

 void ScaleSliderUdate (float value)
 {       
     gObject.transform.localScale = new Vector3(value, value, value);
 }

}
