Add buttons over image pop-up

Hi everyone,

Working on a site for my company and we have a anatomy infographic that we’d like to add circle buttons to that will display additional information when selected etc. This will be on a Case Study page that is accessible from the About Us page. Any help is greatly appreciated as I am new to Webflow and have hit a roadblock in design. I also have screenshots below of the current layout and you can view the read-only link below

Here is my site Read-Only: (Webflow - PMotion Homepage)
