Once Click Accessibility Plugin Customization

Hello!

I am using a plugin called One Click Accessibility on a website that I am building on Elementor.

I can get around well enough for my uses with HTML/CSS, but I cannot figure out how to customize this plugin.

Mainly, I want the menu when clicked to display above the icon that is sticky to the left side of page - instead of below. I imagine this is some sort of JS edit - any help would be greatly appreciated.

Also would love to know how to upload a custom icon instead of the stock one.

I have already found the proper classes while inspecting, but no matter what class / combination I target I have not been able to make a change to it successfully.

Website link (Still in dev)

The item in question is the green wheelchair icon sticky to the left side of page.

Thanks again for input!
