Silencing shutter sound on iPhone camera

Apple Support’s solution (see below) to reduce or silence the iPhone camera's shutter sound also reduces or silences the volume on video playback sound, so when video volume is then turned up so it can be heard, the loud shutter sound is back again.. NOT a useful solution. Turning on the ‘Live’ feature silences the shutter sound, but it seems like there should be a way to silence the shutter sound without being in ‘Live’ mode, just like keyboard clicks can be silenced.

Apple Support Solution:

Change the volume of the shutter sound in Photo mode

1. In Camera, switch to Photo mode.
2. Open Control Center, then drag  up or down.
3. Swipe up from the bottom of the screen to go back to Camera.
4. Note: The shutter doesn’t make a sound when Live Photos  is turned on (except in some countries and regions).
