I am Unable to identify the Element

In my application, there are multiple expand buttons next to a particular text. I am sharing the screenshot. I want to click on a particular text expand button. Like now if I click 3 expand button option of a text, next time that expand button of a text should move to 4 options. I am sharing the HTML code.

I try to find image match, click image and other option but I am unable to identify the Element.

Please anyone help me.
