Upload file using Robotic Process Automation

Thanks for the reply. I think I understand more about it.
Right, there is no ‘input’ element. this is inbuilt IBM ECM product component that built on DOJO framework and necessary supporting technologies. Nothing is there to change that UI now. Now you can see the Browse element for reference attached screenshot.

Alternatively I have tried with ‘AutoIT’ using .exe (inside I gave the full path of the file) but it loading single file. But I want load couple of files at a time

snippet attached for reference.
Run AutoIt Script C:/Ride_Workspace/KOLEA_AUTOMATION/autoupload/auto5.exe

mentioned path is referring the exe file which has file path. But not sure how to pass multiple files path.

Please help me asap and thanks for the spontaneous reply.
