The browser will still pop up, but for the browser automation to work in the background such that it does not take control of your mouse or keyboard, you must use SimulateClick and SimulateType options for the activities in your process. SendWindowMessages may work, but this can require that the browser be in the foreground.
In the browser there is a drop down. So i am using Select Item. But in Select Item there is no option SimulateClick or SendWindowMessage in the properties.
I am not asking what to use between Simulate click or Send Window Message ?
My question is “is it mandatory to use simulate click or send window message in production?” Because the production machine won’t be in visible mode. It will be completely unattended.
No, it’s not mandatory. It’s just suggested wherever it’s possible, since UiPath can perform simulated activities more quickly, and if anything interferes, such as an unexpected popup, the process is more likely to complete anyway.
