Why can't I scroll through TrustPilot reviews on my website?

[bignigga]

The code is not functioning fully. I want to add a TrustPilot review to this website: https://wecro.de/products/bianca. Then, look under the products for the TrustPilot reviews; you can scroll through them. However, I can't move it left and right, or does it automatically move to the right. What can I do to adjust this and make it appear as on the website added here? Currently, it looks like this on my website: https://aerify.store/products/pro-schuhe. Please check the attached code! Thanks in advance! ❤️
