The only thing you need to do is to specify a Jitsi Server in the module configuration.
If you do not have your own Jitsi server, a list of some tested public servers is provided in the configuration.
In case you've overwritten the default content security settings, you should make sure following resources are allowed:
script-srcframe-srcExample common.php snippet:
//...
"frame-src" => [
"self" => true,
"allow" => [
"https://www.youtube.com",
"https://your-jitsi-server.tld",
]
],
"script-src" => [
"self" => true,
"unsafe-inline" => true,
"allow" => [
'https://your-jitsi-server.tld/external_api.js'
],
//...
Note: The default csp should not block any of this.
