How to set up and customize lightdm-pantheon-greeter?

Question

linux

Hello community!
I have been using elementary OS for a long time, during this time I configured it completely for myself, except for one thing: I could not configure the system lock screen (in elementary OS it is called lightdm-pantheon-greeter). I tried to set it up as regular lightdm is set up, by going into the config, which is located in /etc/lightdm/lightdm.conf, but in the elementary it is not so arranged, and its configs (which I found, at least) do not even have a hint of that they can be configured and customized. I want to change the lock screen icon theme, mouse movement speed, and idle screen fade time. It would seem that everything is not so difficult, but in elementary it led me to a dead end. Thank you very much in advance.
PS I ask in advance holivars and ordinary trolls, who, instead of help, will either tell you to switch to Windows, or change the distribution kit / environment / name / gender / place of residence, go through the forest. I expect to see an answer to my usual simple question
