By desktop do you mean the jitsi call widget thing? Instead of the native call support that I believe element x uses?

Do the voice call and video features work with continuwuity?

Seems interesting, some problems I see. The author seems to have forgotten that not everywhere has surnames and some places have multiple surnames. Would have been better to just have a “name field”. Would make this more universal.

This is on /c/Foss so I assume the OP was asking about Foss options for translation.
