In Hyprland, how it works is that you define the screen lock command (e.g. swaylock) in hypridle and that gets wired into logind somehow such that you can loginctl lock-session. I then (also in hypridle) define a before sleep hook that locks the session. I believe the proper way to do this would be to run your lockscreen as a systemd unit that is WantedBy and Before suspend.target. This would in theory take care of making it idempotent and reliably show the lockscreen before initiating suspend. A friend of mine has this sort of setup and, while it is reliable, the lockscreen is still racy and sometimes only triggers after suspend. Might be the lockscreen unit not signalling its readiness to systemd properly though.
