By default, this is "https://matrix.to" to generate matrix.to (spec) permalinks.
Set this to your Riot instance URL if you run an unfederated server (eg:
"https://riot.example.org").
1. `jitsi`: Used to change the default conference options.
1. `preferredDomain`: The domain name of the preferred Jitsi instance. Defaults
to `jitsi.riot.im`. This is used whenever a user clicks on the voice/video
call buttons - integration managers may use a different domain.
1. `externalApiUrl`: The URL to the Jitsi Meet API script. This is required
for showing any Jitsi widgets, no matter the source. Defaults to
`https://jitsi.riot.im/libs/external_api.min.js`.
Note that `index.html` also has an og:image meta tag that is set to an image
hosted on riot.im. This is the image used if links to your copy of Riot
