How do you get rid of the green bar on the top of your phone when you are in a call, but another app

[Android Central Question]

the green bar also shows the call duration, Whenever I get on Instagram or try to get on another app, it always stay on the top, so if there is something on the of the screen I have to press, I'm not able to click it otherwise it takes me back to the call, I have a ZTE Blade X Max, And I have been struggling with this issue for quite a while, I know that the bar is removable, because on my last phone, the ZTE Grand X Max 2, everyone said you weren't able to get rid of it, but I was able to. All help is appreciated, thank you.
