How to click on a different location of the progress bar to create a div? at the current location

above is an audio plug-in wavesurfer.js. There is a gray progress bar below. Now click anywhere in the progress bar to create a div (red circle area) at the current location. Click x to delete the div, and drag the two-way arrow to drag back and forth, as shown. I am now writing the result is to click on any location to show only one is stacked together, how to solve?
specific results can be found on the website
