, why cant you just hold your finger on the volume bar that shows youre on wifi? Instead

Your phone is connected to Bluetooth (car adapter) and you’re inside trying to use Instagram. When you hit the volume up it shows you’re connected to Bluetooth. Why can’t you at this point just press on the screen where it shows Bluetooth in the volume bar? Instead you have to swipe from the right top corner down to open the control centre, press on the Bluetooth, scroll down to your device, click on the device and hit disconnect. ???
