This so much.

Also I'm a big fan of chat-bots. How about a chat-bot that answers typical HR questions for an organisation?

"How much leave do I have remaining this year?" -> 16 days.

"Book the dates 10/5/2021 to 11/5/2021 as leave" -> Confirmed. Request sent to your line-manager.

etc...

I've seen so many bespoke web pages for these sorts of tasks. Including emailing someone in HR to do it for you.

I'm sure a system exists, but too lazy to google for it :)
