Z-index override
tip
Use this feature if you have issues with the chat button getting hidden by, or hiding, other elements in your store's UI.
Description
The z-index field can be set to any numeric value, with higher values pushing the button toward the front of the screen and lower values pushing it toward the back. The default value when unconfigured is 999, which will place the button atop most elements.
When trying to find a value to bring the button above or below an element, increments don't need to be very granular, and you can adjust the value by 10, 50, or even 100 at a time until you find an override that works.
