How to remove the eye-slash button in preview mode?

I'd suggest extending the original Preview command

Thank you for reply @artf . Is there any documentation or sample code about extending an existing command?

@niveth09 here is the code for extending the preview command without the eye button:

    const cmdVis = 'sw-visibility';
    commands.extend('preview', {
        run(editor, sender): void {
            this.sender = sender;
            this.selected = [...editor.getSelectedAll()];
            editor.select();

            if (!this.shouldRunSwVisibility) {
                this.shouldRunSwVisibility = editor.Commands.isActive(cmdVis);
            }

            this.shouldRunSwVisibility && editor.stopCommand(cmdVis);
            editor.getModel().stopDefault();

            const panels = this.getPanels(editor);
            const canvas = editor.Canvas.getElement();

            panels.forEach((panel) => panel.set('visible', false));

            const canvasS = canvas.style;
            canvasS.width = '100%';
            canvasS.height = '100%';
            canvasS.top = '0';
            canvasS.left = '0';
            canvasS.padding = '0';
            canvasS.margin = '0';
            editor.refresh();
            this.tglEffects(1);
        },
    });
