How to get mod to be applicable in multiplayer?

I have unmodded game, latest ver. 1.82
Have DLCs:
Mega Events, Revenge of the Snathi, Ship Designer's Toolbox, Mercenaries Expansion Pack
Tested on my main machine and on laptop.
Faction available, no errors.
I know I may be called noob, but I stick to "vanilla experience" after some bad experience with GRM ("who is not using GRM these days anyway???", well, here am I... at least me from which I know). Please do not mess with the shipsets, or it will stop validating this faction on game startup.

Yeah, sorry, ships aren't going to happen. I've given up on this game and I'm moving on to Stellaris.

This really needs a custom shipset, still a good mod.

totally read that in the codex narrator voice.
