Our sections with waves support a custom separator in between the wave content:
You can adjust this by adding an HTML symbol to the Custom separator box:
To find which HTML symbol you'd like to use, we recommend heading here: https://www.toptal.com/designers/htmlarrows/symbols/
Then find whichever icon you'd like to use, and copy the HTML Code value into the Custom separator field above.
Feel free to reach out if you have any issues!
