Katalon Docs

Please Refer to the above documentation, can you explain me the following

WebUI.click(findTestObject(‘Page_CURA Healthcare Service/a_Make Appointment’)), Please can you kindly explain how did you get that object, I do not see that in the “Inspect” window I see the following

WebUI.setText(findTestObject('Page_CURA Healthcare Service/input_userName'), username)
		WebUI.setText(findTestObject('Page_CURA Healthcare Service/input_password'), password)

Please can you kindly explain, how did you get this web element, Page_CURA Healthcare Service/input_userName and
Page_CURA Healthcare Service/input_password

  1. Is there a way, I can give test input in Cuccumber via excel, if so please can you help me out how?’

Thanks in advance and this is my first Katalon experience.
