Accordion open/close icons in the beginning of labels rather than end

Hello,

I reach out once again to your wonderful support team. My question is pretty much a copy of this other post: https://onpointplugins.com/plugin-support/icon-in-front-of-the-menu/ 

I tried fiddling with the suggestion posted in the other post, but was not able to make it work. Is it possible to move the open/close icons at the beginning of the labels instead of end?

Look forward to hearing from you.
