vaadin 23 how do i get my grid to autoupdate every few minutes?

I'm new to vaadin and currently I'm doing this project at work and have to make a grid autoupdate from the database, can anyone help me?

I've looked around for documentation and tried using TimeTask but it did not work.

You need to enable Push in your application in order to send asynchronous updates to the client. Here, asynchronous means something that doesn't happen because the browser sends a request to the server, so for example something that is executed with a timer.

In Vaadin 23, enabling Push is done by adding the @Push annotation on a class that implements AppShellConfigurator, typically the Application class. Updates from a background thread need to use the ui.access() method to avoid conflicts in the session. There are configuration options for using Push that you can find from the documentation: https://vaadin.com/docs/latest/advanced/server-push
