Search in bpmn palette elements

How can i make search in the bpmn palette elements? I know there’s a feature to search in the diagram, but is there a way to customize this search to the elements in the palette or make search in it by another way ?

Is there a specific why you want to do that? The number of actions in palette it quite low

As we will add a large number of custom elements in the palette, so we need to search in them

There doesn’t exist any solution like this. You would to create this on your own, but maybe you can inspire by the SearchPad implementation and create a search provider who would do the trick
