How would I go about making a smooth transition to plymouth from lightdm with this greeter

Apologies if this is not the right place to ask

Environment

• OS: Arch
• nody-greeter version: output of nody-greeter --version

Description of feature

I set up a custom systemd override for lightdm to make the transition from plymouth smooth like described here https://wiki.archlinux.org/title/Plymouth#Smooth_transition

However I still have a black screen for about 2 seconds after the boot animation, but with a mouse cursor. That is why I think the greeter is running by this point, but there is still no output until the ui loads

Can I do something about it ? Or can you ? Or is it only a lightdm issue or a plymouth issue ? I don't really know.
