Learn how (and why) to enable WebGL for an extension.
In the Developer Portal, some extensions have a Requires WebGL option. If this option is enabled, Canva only shows the extension to users who are using a WebGL-enabled browser. If your extension depends on WebGL, you must enable this option.
Canva only supports WebGL 1.x — not WebGL 2.x and beyond. This is because some modern web browsers, such as Safari, don't enable WebGL 2.x by default.
