[Feature Request] Client-side solution to add custom emojis

[PL7963]

I'm in a server with Discord Chat integration. But I couldn't memorize every emoji name. I would like to have a mod let me just preview emojis and auto-complete them. Also I'm not the owner of this server. So I cannot add install datapack to the server. I've seen a similar project, Emojicord, they allow users to add emojis from discord server on client side with a json file in config folder. Is it possible to implement it in this project?
