            .addToolButton(ToolbarButtonType.SQUARE, DefaultToolbars.ButtonId.SQUARE.value())
            .addToolButton(ToolbarButtonType.INK, DefaultToolbars.ButtonId.INK.value())
            .addToolButton(
                ToolbarButtonType.FREE_HIGHLIGHT,
                DefaultToolbars.ButtonId.FREE_HIGHLIGHT.value()
            )
            .addToolButton(ToolbarButtonType.IMAGE, DefaultToolbars.ButtonId.IMAGE.value())
            .addToolStickyButton(ToolbarButtonType.UNDO, DefaultToolbars.ButtonId.UNDO.value())

Hi,

Thanks for contacting us. In this case, I recommend calling the following in onResume:

        mAnnotationToolbarComponent.setItemEnabled(DefaultToolbars.ButtonId.UNDO.value(), false);
        mAnnotationToolbarComponent.setItemEnabled(DefaultToolbars.ButtonId.REDO.value(), false);
