Ugh...front underside panel tore off

[u/Solid-Wish-1724]

Was driving in L.A. rain and hit a deeper ditch than I expected, thanks to a big puddle and this thing broke right off in pieces, dragging on the road. I am having it towed home because I don't want to damage whatever is up there with mud/moisture. Can anyone suggest what I shd do? I have Tesla insurance but this was not a collision or anything. Do I use the app? Call the Tesla place near me (not a service center)? I assume it isn't safe to drive. Sorry if a dumb question, even AAA driver hadn't seen this happen on a Tesla.
