You can leave it.

As long as you ran systemctl daemon-reload, you should be able to try sleeping without needing to reboot.

It might be due to https://github.com/systemd/systemd/issues/33083.

Try disabling user session freezing when sleeping:

sudo systemctl edit systemd-suspend.service

Add the following to the file:

[Service]
Environment="SYSTEMD_SLEEP_FREEZE_USER_SESSIONS=false"

Reload systemd:

sudo systemctl daemon-reload

After that, try sleeping and waking again.
