How to auto renew LE cert

The LE cert expired few weeks ago and my website went down - switched back to self-signed cert.
Strict SSL (Cloudflare) didn’t work anymore, and I had to switch to Full mode to put it back online.
The link below said CbPanel auto-renew LE cert, but it didn’t. [1]

Is this still a pain or we can tell CbPanel to auto-renew LE cert ?

CbPanel: 2.3 (fresh install)
OS: Ubuntu 22.04

Thanks
