Node-red-node-ui-table, csv and pdf download

Hi everyone.

I'm new to NODE-RED and I'm trying to use node-red-node-ui-table. Miraculously I was able to build a table and format it as I wanted. I would like to try to export the data in csv and pdf format.
I have seen other similar thread, but I cannot understand how and what to send for the command to be able to save the data in csv or pdf.
Can someone help me how the "payload" should be sent. I only understood that the "table.download (" csv "," data.csv ") must be sent;" but i didn't understand how, through "msg.ui_control"?

Thanks for any help!
