Decrease the gravity in half for 10 seconds

Question

   void gravdown()
     {
         StartCoroutine(downgrav());
        
     }
 
     private IEnumerator downgrav()
     {
         //codes
     }

I have a button. And when this button is pressed, the current gravity value has to be halved for a time like 10 seconds and then return to its original state. When I did some research on how to do this, I came across coroutine. But "IEnumerator downgrav ()" I get an error in this part. CS0161 '': not all code paths return a value coroutine ". Since it's something I've never used before, I don't know what to do. How can I do what I want?

 private IEnumerator downgrav ()
 {
     Vector3 initialGravity = Physics.gravity;
     Physics.gravity = initialGravity * 0.5f;
     yield return new WaitForSeconds( 10f );
     Physics.gravity = initialGravity;
 }

If you are getting that error then change the coroutine to a method, you are not using anything from a coroutine
