My Samsung Galaxy M20 phone screen stay on during call

[RanjeetBengaluru]

Where is the setting in Samsung Galaxy M20 to "turn off the screen during

 calls"? It is the proximity sensors setting that is not there into this phone. My phone keeps its screen on while on call. Creating lots of issues.
Please help.
I checked following options: Phone==>menu==>setting, but there is no option to "turn off the screen during calls" in Samsung Galaxy M20.
Please help.
