iframe is blocked and our frame-src CSP is https://viewer.diagrams.net https://www.draw.io https://*.google.com; for security reasons. You'd have to host your own instance with the following DOM_PURIFY_CONFIG:

window.DOM_PURIFY_CONFIG = window.DOM_PURIFY_CONFIG ||
    {ADD_TAGS: ['use', 'foreignObject'], FORBID_TAGS: ['form'],
    ALLOWED_URI_REGEXP: /^((?!javascript:).)*$/i,
    ADD_TAGS: ['iframe'],
    ADD_ATTR: ['target', 'content', 'pointer-events',
        'requiredFeatures']};
