Assistance from any modder how to manually install Mods in the steamapps game directory

[Bosn28]

So I downloaded Mods from Nexus Mods for Dissidia Final Fantasy NT the game is not supported by Nexus Mods yet. I am not a modder I don't speak tech or coding. So after several responses from different people on other gaming forums and reading several things how to do this and watched several YouTube videos nothing had worked. So I'm asking any modder or tech savvy computer person to please give me an easy/ beginner in-depth breakdown how to manually install the Mods into the games steam directory on my C drive. I have also requested Nexus Mods to add DFFNT as a supported game so I can use Vortex Mod Manager so I can download the Mods to the manager and let it put the Mods into the directory correctly. This was suggested by several other people to request the game become a supported game. Any knowledge and guidance would help and be gratefully appreciated. I also have zoom and Facebook messenger if you would like to video chat and walk me through the process.
