Z-index is a term used to define where one HTML element sits numerically amongst others. The order is important as elements with higher values will be visible above those with a lower index.
The tawk.to widget defaults to a z-index of 2,000,000,000, a relatively high value, as it frequently needs to sit above other HTML elements. Using a lower index can often result in the widget operating normally but being invisible to visitors, as it would be hidden by other elements on your web page.
Just add the center portion of the code below (lines 4-7) to your widget code before the end of the script as shown and replace the z-index with your desired numerical value.
