mattermost-desktop: Audio and video calls not working

[bellackn]

Nixpkgs version

• Unstable (25.05)

Describe the bug

When I start a call in the app (by clicking 'Start call' in the upper-right corner of a direct chat), the app logs the following:

[642511:0319/143348.825067:ERROR:gl_surface_presentation_helper.cc(260)] GetVSyncParametersIfAvailable() failed for 1 times!
[642511:0319/143359.888463:ERROR:gl_surface_presentation_helper.cc(260)] GetVSyncParametersIfAvailable() failed for 2 times!
[642511:0319/143404.822824:ERROR:gl_surface_presentation_helper.cc(260)] GetVSyncParametersIfAvailable() failed for 3 times!

Then a 'Connection failed' window pops up.

When I click the small camera icon in the right sidebar and then the 'JOIN MEETING' button in the chat, the app logs:

I don't know where I could give these permissions other than in the server settings. I have given all permissions there. However, when I click 'Save', the app logs:

4:39:13.261 › [App] [ServerViewState] there was an error in the edit server modal: TypeError: r.systemPreferences.getMediaAccessStatus is not a function
14:39:13.276 › [App.Config] config.autostart has been configured: true

Please let me know if I can be of any help! And thanks for maintaining the package.

Steps to reproduce

1. Open mattermost-desktop
2. I assume that there's a server where you're logged in to.
3. Click any user in the the 'DIRECT MESSAGES' section.
4. Click 'Start call' in the top-right corner to observe the first described error.
5. Click the small camera icon in the right sidebar and then 'JOIN MEETING' in the chat to observe the second described problem.

Expected behaviour

I can join calls and Jitsi meetings from within the mattermost-desktop app.
