The activity that will return a Boolean value is 'Image Exists'. 'Image Exists' is specifically designed to check the presence of an image and returns `true` if the image is found and `false` otherwise. Other activities like 'Find Image', 'Wait Element Vanish', and 'Element Scope' do not directly return a Boolean value.
To run a process in the screen's background using Excel activities, the 'Visible' property must be configured. Setting this property to False allows the Excel application to run without being displayed on the screen, thereby enabling background processing.
Renaming an argument from the Arguments panel automatically updates the argument's name in all activities that utilize that argument within the current workflow file, ensuring consistency and reducing the risk of errors.
