Interface PickButtonOptions

Where the button is rendered (default: the title bar).

Ignored for buttons attached to an item via PickItemDisplay.buttons — VS Code always renders those inline on the item itself.

Makes this a toggle button with the given initial checked state.

VS Code updates checked in place on the returned button before firing its trigger event, so read the state back off the same button object inside the handler rather than tracking it separately.

Tooltip shown when hovering over the button.
