How to automatically save the attachments in firefox from Katalon

Hi,
Most of my test cases are related to downloading files from the browser. I find an issue in downloading files from firefox. I want to actually download the attachment automatically without prompting to save/open. I went through all the answers posted in the katalon forum but none helped. I have the below settings configured from Desired Capabilities → WebUI–>Firefox but it is not working

Could someone please help?
