How to tell when the print is started and all properties are populated?

My brother and I got a P1S late last year and I am often printing stuff for him. He was constantly asking for updates, so I set up a discord server and am using the discord HA integration to send updates. One of the biggest challenges is sending an update on "start" where all the values are property updated. For me that means Print Weight/Length and the Cover image.

I've tried using the "PrintStarted" event, but that fires before the m3f file is downloaded and the rest of the data is updated.

Anyone know how I can tell when the file is completely downloaded and all the data is populated? I would rather not wait until it actually starts printing, and some of our prints have had quite large m3f files taking a minute or 2 to actually download.

In addition, I've found that sending a picture on "finish" is hard because the bed has completely lowered. I've also not found a good way to know when the print has completed, but bed has not completely lowered. This one is a bit less important.
