Home button on iphone

Hi, my name's Hoa. I have a question. Why in IOS 14 home button always on in screen, it's very terrible for me because when i using my phone for work, game, chat,... i usually touch in home button and go home screen. Last time in IOS 13.7, i must put home button twice, it hardly to discontinous my phone use process. Have i turn off home screen look like before IOS 13.7?
