Traccar new interface

Hi,

I have cloned the github repo using git clone --recursive https://github.com/traccar/traccar.git
The old version of Traccar runs successfully.
There is no option to switch to modern interface

How do i ensure that option shows and points to modern interface.
How to load modern interface by default.
How to brand modern app change traccar logo

add /modern to the request url or redirect

You also need to compile it first.
