Note
This ownCloud extension is a community extension and is not officially supported by ownCloud.
To install the extension, follow the official documentation to load the extension.
By default, Excalidraw will try to download all the used fonts from the Excalidraw's CDN. In order to allow the fonts to be loaded, you need to add the CDN's URL to the oCIS CSP configuration.
Alternatively, you can self-host the fonts. You'll have to copy the content of the Excalidraw's fonts directory to the path where your assets should be served from.
In that case, you should also set window.EXCALIDRAW_ASSET_PATH to the very same path, i.e. / in case it's in the root:
window.EXCALIDRAW_ASSET_PATH = '/'
