Can you recommend me software similar to Skype?

[volterral]

Hello,
I've been having issues with Skype lately and I'd like to replace it with another software. I use it mostly to make group voice calls and share my screen with the group, so this feature is a must-have. Preferably software that's part of the official Ubuntu repositories (no snaps) so I don't have to deal with external PPAs like I had to do with Skype. I noticed Telegram is available in the official repos but I did some research and it apparently can't do group voice calls or sharing the screen with various users.

What do you recommend?

Thanks in advance.

zoom for screen shares. But it's more like webex than skype, everyone has to call in.

Slack works pretty well for voice calls.

Pretty sure neither is in the repo.
