Is it possible to connect a client mod and a Bukkit plugin

I wanted to ask if it is possible to connect a client mod and a plugin i.e. that the client mod sends a message to the server, which is then forwarded to the plugin and edited there and then sends a message back to the client.

For example, the client mod sends the message "Hello Server" to the server when joining, and when the plugin receives the message "Hello Server", it sends the message "Hello Client" to the client to the client mod.

Information:
Version: Minecraft version 1.18 is supposed to have the server and client.
Information: Version: Minecraft version 1.18 is supposed to have the server and client. Launcher: It would be best for me to have a Fabric Launcher, but I can use Forge too

PS: Sorry if this is the wrong forum for this question
