What happens *exactly* when clicking on "Join Meeting"?

[pandel]

Hi!

Sorry for the somewhat strange question. I try to describe what I want to know and why:

(We use Mattermost desktop client under Windows. Plugin Version 2.0.0)

In our environment different browsers are being used for different use cases. The browser that should start for a single use case is being controlled via different URL protocols, i.e. http:// and https:// open (an extremely cut down version of) Firefox for normal web browsing, videochat:// opens Chrome (but only single destination, no general web browsing allowed here), and some other do other things... I won't discuss why it is done like this, because we are not able to change this behaviour.

Keep in mind, we are using the current (v4.6.1) desktop client.

Now, if I setup "Jitsi Server URL" under plugin settings to contain https://our.jitsi.server it opens Firefox (under which video chat won't work), but if I set it to videochat://our.jitsi.server nothing happens, although videochat is registered as own URL scheme under Mattermost settings and opens Chrome under normal circumstances (via link inside message i.e.).

I know that it should work: as a test, I a) copied the link URL which was created via the plugin and b) re-post it as a normal Mattermost message, c) click on the resulting message link and d) Boom! Chrome starts and everything is fine.

And even more strange, if I don't use the desktop client but i.e. Firefox as Mattermost client, the plugin works as expected: "Join Meeting" starts the Chrome browser via the videochat://URL Protocol.

So, I try to understand, why the "Join Meeting" button won't react to the videochat:// based link, but to the https:// one inside the desktop client. I already tried to find the solution in the plugin source (and messed around with the meetingLink), but as I have nothing to do with Mattermost plugin development I don't quite understand the complete mechanism to make changes for my needs. I assume it might have something to do with onClick={this.openJitsiMeeting} in post_type_jitsi.tsx, but, you know...

Perhaps you can lead me into the right direction.

Many thanks and regards, Holger

In theory, when you click the link, it checks if it should open the meeting embedded, or in a new window. If it has to open the meeting in a new window, it should just open a new window (using window.open(meetingLink, '_blank'). That is all the plugin does. Does this bring some light to the matter?
