Mod RedM singleplayer

Hi, I was wondering if it’s possible to mod RedM single player with mod menus and the new police mod coming from the LSPDFR people.

What? Can’t you just do that in Base GTA V or even FiveM SP? And also, gta 5 mods won’t work in RDR2 much like rdr2 mods wont work in gta 5 regardless if they use the same engine or not

you really didn’t understand a single thing this man said huh?
