Replace PureFTP with ProFTP to enable SFTP

I would like to replace PureFTP with ProFTP as I’ve read that PureFTP doesn’t support SFTP. I would like to give my clients SFTP access to their domains (without them needing an SSH key, just with a username and password) and would really like to be able to control these accounts via Cyberpanel.

Now I am new to CyberPanel and could use some help on how I can achieve this. Any advice is welcome and appreciated.

I run CyberPanel on Ubuntu 20.04 LTS and OpenLightSpeed (Vultr).
