In the Olivero theme, the pagination is not as per the Figma design. The Pagination is different than it is in the Olivero Figma design.

Make sure you have selected the Olivero theme and open it using Chrome or a similar browser and add a good number of content like articles in order to check the pagination. For less content pagination wont be there.
