There's a template. You invite the company into an all-hands. You tell the entire company. During that, account lockouts are happening. Then, you have individual appointments between the individual manager and HR (sometimes, HR+). The meeting itself is short and gives the details of the separation.

Yes, it will have to be a zoom call, but the CEO does not make it about themselves, and sticks to a script that's been rehearsed and checked with multiple humans to show empathy and humanity.

You can tell the survivors that some of the people who were cut were poor fits for the company and any details you want, but sometimes it's the details that show low emotional intelligence rather than the fact of the call itself.

Most people don't have suggestions, they just have complaints. If you've never been in the position as a business leader where you are forced to lay off employees then it can seem capricious.
