Instructions for creating a floating menu inside a repeating group
1. Create a reusable element containing an icon/button and a group focus, this is gonna be the menu, so that's where you should add the menu elements like the options etc.

2. add a custom state called 'option' to the reusable element and create an action to fill this custom state with the option chosen by the user, it should be of type text.

3. place the reusable element into the repeating group.

4. place the 'Data trigger' element from this plugin into the repeating group, it has a field called 'Expression' that should be filled with the value from the custom state of the reusable element.

5. use the plugin event called 'A data trigger fires an event' to start an action after the user clicks an option from the menu.

Tip: you can add a data together with the option.
