How to activate HTTPS for noobs?

Hi all,

I just finished installing CasaOS and some apps on my Raspberry Pi 5 server. The connection is still over http so i’d like to make it https but the guides i found on the internet are either too complicated or not for casa os. Is there a written or video guide i can follow that easy to follow?

PS, I’d like to run pi-hole and wireguard vpn on this server later.
