When will we be able to make audio and video call by whatsapp for linux?

[SouRod]

I use Ubuntu 22.04.2 LTS but I haven't found any open source application that has audio and video calling options. (Even whatsie).

All Linux clients are wrappers for Whatsapp Web. Calls are only available on the official Whatsapp Desktop, which is only available for Mac and Windows. So you won't see that working on Linux unless you try to run Whatsapp Desktop for Windows via Wine, find some Linux wrapper that also uses Wine underneath or wait forever until Meta implements a Linux version.
