Trigger on agent component tables

Hi Convex team, I'm working with agent component but running in some problem, the problem is because the tables are maintained internally, I'm not able to use trigger with type safty

// register a function to run when a `ctx.db.insert`, `ctx.db.patch`, `ctx.db.replace`, or `ctx.db.delete` changes the "users" table
triggers.register("users", async (ctx, change) => {
  console.log("user changed", change);
});

// register a function to run when a `ctx.db.insert`, `ctx.db.patch`, `ctx.db.replace`, or `ctx.db.delete` changes the "users" table
triggers.register("users", async (ctx, change) => {
  console.log("user changed", change);
});

I want to use the messages table from agent component here but I'm getting type error, what could I do? Thanks

This is intended to work a but different. https://stack.convex.dev/triggers it is meant to be registered and then it creates new mutation function. You are supposed to use this instead of the mutation from api. This will trigger the source mutation… I don’t think you can use it for components as you don’t have acces to the mutation functions used by components. You may have an onfinish step somewhere in the agent. That should be a valid way to get messages as they are sent

This thread contains some insights from Ian on why the API boundary exists that prevents direct access to component resources, one of the biggest being breaking changes if a component's internal design is modified: https://discord.com/channels/1019350475847499849/1379981117083619463
