Hello @Inesita,
Unfortunately, it is not possible to achieve the desired result with the available elements of Elementor. The website you provided is not built on XStore or Elementor widgets, so the only possible way is to use the shape divider. We have prepared a video tutorial for you, which you can watch here: https://www.veed.io/view/74434556-1527-4a83-be00-ded8d6f6464e?sharingWidget=true&panel=share.
You can customize it according to your needs. Additionally, you can try to use any third-party plugin that better meets your requirements, but you do so at your own risk.
Best Regards,
8Theme’s Team
