How to install a siren mod?

Anyone know how to install a siren mod with FiveReborn??

I tried to install normal, didn’t work. Thanks for your help!

No special way to install it. Same way as original GTA

I think you mean server-sided ?

Please be clear on the way you would like to install it. Client-sided or Server-sided?

There is only one way to install mods right now, wich is client sided.
