Kindly Add Mute button – imo-International Calls & Chat Review

I use IMO regularly to have a video call with my family and friends specially a group call its a great feature to have a group video calling but just a small addition can make this app perfect which is a mic mute button if someone is not speaking in group call at least can make his or her mic mute so that others can have a chat clearly. Kindly rectify this if it’s possible. Thanks
