There are two SciFinders in the "Add-on" search options.

Mac OS Big Sur v11.6

Question: In the “search” Add-ins, there are two for SciFinder. The one immediately to the right of Reaxys has no icon or picture of the structure in the window. The second one has the SciFinder-CAS logo, and a picture of the structure. Is this correct? What is the difference between the two options?
