Set ContextMenuOption to None to hide all context menu options. The default value is RightClick.

Example: Disable context menu

<button id='disable'>Disable ContextMenuOption</button>

// Disable ContextMenuOption
document.getElementById('disable').addEventListener('click', ()=> {
  viewer.contextMenuOption = 'None';
});

This hides the context menu and prevents right-click interactions in the viewer.
