TextMeshPro Doesn't work with the new input system

So I've recently integrated the new input system to my game but input fields don't work for some reason and I've renamed a class temporary to Input so in the error box it could show everything that was using the input box so it can say that for example GetAxis("Horizontal") isn't in the class, so if there is no update or fix to that how am I supposed to do something like input.simulatemousewithtouches and complicated things like this in the new input system.

but if there is a way to upgrade or a fix to it please let me know

Hey thanks for the help, but what am I supposed to write in the part of the using new Input system?
