Key information includes: the `name` of the thumbnail resource, an `expression` to compute the image, `fileFormat` for output encoding, and `bandIds` to select specific bands. `visualizationOptions` allow for 8-bit RGB visualization. An optional `grid` defines image reprojection and clipping. Finally, the method `create` generates an ID to render a thumbnail image.\n"]]
