With mouse and keyboard steep on ps4?

Hi, I recently bought a steep and would like to play on the PS 4 with keyboard and mouse is that possible? If yes how?

I recommend Steep with a controller. It's more fun, and easier, too.

This only works in a few games on ps4 and it is also very bad if it does not work

I advise you to play Steep with a controller ^^

I started Haltsteep with a keyboard that's why I find it so easier

I prefer the keyboard
