App Menu
An app-style navigation bar pinned to the bottom of the screen on small devices. It is shown in the block inserter as Canvas App Menu and registered as canvas-core/app-menu.
Select the block on a page and its own settings open in the sidebar, in the panels below:
Settings
Each setting is named exactly as the block editor names it, followed by what it does and what it starts as. Where a setting carries a Shown when line, it stays hidden until that condition is met, which is the usual reason a setting looks missing from the sidebar:
