Add a new section or block to an existing section, then click on the "Apps" tab to search for the desired Snap Block.
In this example, we're adding the "Previous - Next Navigation" block.
The block will only be visible for products within a specific collection. You may need to adjust the preview URL.

Or a more classic look.
