Find some element on modern traccar

Where can I find this class in the code marked with the red color :
https://ibb.co/CsL4CS7

I think that's it
https://github.com/traccar/traccar-web/blob/master/modern/src/common/components/BottomMenu.js

But which class to use, I want to hide that bottom menu from the map ?

Hello, does anyone know where I can remove the Traccar logo and place mine in the start (Login), I'm trying Traccar 5. Thanks
