How to keep the toolbar (search, filter etc.) after I select rows?

How to keep the toolbar (search, filter etc.) after I select rows? I want to be able to search when I select rows.

I also want to be able to remove the delete button and replace it with my own buttons. I understand that I need to do it with;

`customToolbarSelect: (selectedRows, displayData, setSelectedRows) => void `

But I don't understand the parameters. Can you give me an example about this function please? Thank you.

Edit: One more question. How can I download only the data which I filtered out and displayed on the screen?

Begin at the customToolbarSelect callback named in the issue and trace the toolbar-selection API. No files or tests are named; clarify whether toolbar persistence, custom selection actions, and exporting filtered rows are supported, then document examples or define the needed behavior.
