How to put mods on the new launcher? (Stellaris)

As well as the old launcher, slung fashion to mod in your my documents folder, the launcher does not see them, he says to go to their website with the mod. And it is bourgeois, which I aurally perceive well, and the text - not at all. In short: please explain how to install the mods, or how to download them from the workshop. Thank you.
