Hi there,

You can take a look at our [custom annotation examples](https://github.com/pdfjs-express/custom-annotation-samples) to show how to create custom tools and buttons.

I am closing this issue because of very little info. If you still have a question, please follow the issue template and provide us with as much detail as possible.

Thanks!
