Path for category image in BC

Hi everyone.

I hope you can help me.

I had to put images to each item category in BC. For this I made de develope recommended by Yun Zhu at this post https://yzhums.com/34480/

The problem I have is that I need get these images from power automate throw the "Get image or file" box but I don't know which path is the correct one. I've tried all the choice of the combo box but none of them have worked.

Some idea?

Thanks in advance.
