if I view this page in my quest 2 browser it does not offer me the option of going immersive. However, if I take the URL (https://observablehq.com/@donmccurdy/a-frame-vr-example) and run it through the single file exporter by notebook URL (https://observablehq.com/@tomlarkworthy/exporter), the preview has no sandbox restrictions and finally I can go immersive! https://bsky.app/profile/larkworthy.bsky.social/post/3lebptkw24c2d
