Need help adding mods to FiveM server

Hello,
I’ve been lurking around the past few days or so for videos on how to add mods to a FiveM server, but most use OpenIV. I’d prefer to use FiveM since I have the server working already, though it is mod-less. I was looking at mods like Open all interiors, but that mod seemed to not work on the life invader, and the IAA buildings. I’ve tried some other mods too but have no luck having any of them install. Any help would be appreciated.

Thank you so much :smile:
