It is not clear what exactly you are looking to accomplish. Can you please explain further? VideoWall and Gallery View are both describing the same feature, so that much isn’t clear. The two different views you will see in the default UI are gallery view and active speaker view. Using these terms, please clarify exactly what you are trying to accomplish with those two.
Also for your reference I am including the documentation for pinning users and spotlighting to ensure the correct terms are being used in your description for those.
