Please see the screenshot.

I have the requirement to perform Web UI actions on each of those elements subsequently (the three vertical dots). That means click on it, chose a dropdown option etc. Keyboard shortcuts don't work with this type of website framework. But I can get it to work using "Click link on web page" with custom element selectors.
Now, once I've performed the necessary actions on the current item, how to I move to the next (three vertical dots)? Like I mentioned, keyboard tab does not work. Image recognition also only gets me the first ocurrence.
There's javascript and I'm able to retrieve the NodeList with document.querySelectorAll. But same thing, I don't know how to access the subsequent nodes.
Sounds so complicated and there're should be a way to move to the next DOM element and perform the necessary actions.
Any idea?
