Hi @Karina de Freitas Peixoto,
Thank you for posting in this community.
SharePoint UI Kit is a new feature, and as of now, it is used to design site UI to provide a better customer experience.
Since this is a new feature and we have limited information about it, we recommend that you keep an eye on this feature and maybe in the future this design of the feature can be applied to the SharePoint site. I will also keep you informed as soon as there is new information about this feature.
Please accept my sincere apologies for any inconvenience caused!
