In UiPath, the "Element Exists" activity is used to check if a specific UI element is present on the screen. This activity returns a Boolean value (True or False) depending on whether the element is found or not.
You can use the "Element Exists" activity in combination with an "If" condition to perform different actions based on whether the element is found or not. For example, you could use the "Element Exists" activity to check if a specific button is present on the screen, and then use an "If" condition to determine whether to click the button or not.
Here is an example of how you could use the "Element Exists" activity with an "If" condition in UiPath:
1. Drag and drop the "Element Exists" activity onto the canvas.
2. In the "Element Exists" activity's properties, specify the UI element you want to check for by providing the selector.
3. Drag and drop an "If" condition onto the canvas, and connect it to the "Element Exists" activity.
4. In the "If" condition's properties, select the "Element Exists" activity as the condition and set it to "True".
5. Drag and drop the desired activity inside the "If" container and connect it to the "Element Exists" activity.
6. Run the workflow.
This way, the activity inside the if will be executed only if the element exists, if the element does not exist the execution of the workflow will continue to the next step.
