How do I use the Auto Installation Plugin?

[leonid-m]

Hello, longpanda!
Please tell me which Ubuntu distributions are supported by the Auto Installation Plugin, in particular whether it is possible to use this plugin with the distribution ubuntu-20.04.1-desktop-amd64.iso?

Please help me!
Question - is there any way to download my preseed file for the Ubuntu 20.04 desktop live iso image (ubuntu-20.04.1-desktop-amd64.iso) without changing the distro itself using Ventoy?
