Currently, the clickable components in messages use commands.
As this could (in theory) be interfered with by other plugins (such as anti command-spam ones, or authentication ones, or logging/spying ones, or alias ones, etc.) it might be worth exploring the Conversations API that's provided in Spigot.
This allows the plugin to deal directly with the player's incoming messages, and schedule what should be done with the responses. It also stops other plugins/systems from interfering with the messages as well.
