How to hide the un needed shapes in palette

HI ,
I want to hide the 3 below icons from palette. I’m using the below example to start the application in angular. https://github.com/bpmn-io/bpmn-js-example-angular.

Thanks in advance.
palette

The easiest way to do this is simply use CSS. Each icon has a unique class that can be used to select the element and hide it.

Thank you very much for your help

is there a way to do this without using css.
