Other people doesnt see me doing emotes and I dont see others doing emotes, there are any othr thing I need to install or do? Im in a server but not modded with plugin

According to Emotecraft's description, the mod/plugin has to be installed both on the server and the client

You need to install the mod both on both the server and the client.
But You don't need to use the same server and client modloader*
For example emotecraft with a Forge client will work with a Fabric server
You can also use Bukkit servers, emotecraft-version-bukkit.jar is the bukkit plugin
With Emotecraft you can connect to vanilla servers, it just won't do anything.
