ImageActivites by UiPath Team - Image Watermark

I was trying to use the Image Watermark activity however I got stumped by the object option in the Properties panel.

image watermark activity

I tried to find any guide/help to this but to no avail. I have 2 question about them:

  • How is this Object field been used or what should I input?

  • I am also wondering whether it can be used to adjust the watermark image’s size, position, etc via this Object field.

Can any of the veteran users advise me on the queries above? Thanks in advance.
